Trendmetr is a web app that allows users to measure how many times a search term was mentioned on Twitter in the last hour.

Features:

• simplistic web UI
• search terms displayed as dB meters
• links to search terms via Twitter or Twoquick

The Good:

Trendmetr is a simplistic graphical representation of the frequency of various terms or trend in Twitter. Below each ‘meter’ are a couple of links that allow users to search the term on Twitter or Twoquick.

The Bad:

While the idea of a graphical representation of trending topics on Twitter is a good one, the execution of that idea by Trendmetr is woefully inadequate. Try as we might, we could find no way of selecting our own search terms. When we added ‘meters’ we were presented with terms like ‘hate my job’, ‘dinner’ and ‘insomnia’. Trendmetr has the potential to become a useful trend tracker, but in its present form it is nothing more than a diversion.

1 Million Tweets is a web service aimed at having users pay $1 to send tweets to be included in a 1 Million Tweets book.

Features:

• website allows users to create and send tweets for $1 each
• tweets will be included in a book

The Good:

According to the 1 Million Tweets website, one of the objects is to raise money for charity (10% of all proceeds). That is a good thing. The site also allows for promotion of companies and causes via 1 Million Tweets.

The Not-so-Good:

1 Million Tweets isn’t so much an application as it is a project. If you want to pay $1 per tweet to participate in the project, that’s fine. At least some of it will go to charity. Simple math tells us that if one million tweets get sent at $1 each and only 10% goes to charity, then 90% (an awful lot of money) will go to the project developer(s). By sending a tweet through 1 Million Tweets the user is granting an irrevocable license as to the use of its content.

It isn’t for us to say whether this is good, bad or ugly, but there are some things users may want to consider before participating.

twislim is a web app that allows users to find out how slim they are compared to other Twitter users.

Features:

• simple web UI requires entry of weight and height
• display shows as “slimmer than x % of all Twitosphere”
• ability to tweet results

The Good:

If you want to find out how slim you are compared to everyone else, then this could be the right tool for you. It might be possible to track your results over time, if you are trying to lose weight.

The Not-so-Good:

While twislim seems like a nifty idea, especially if you are trying to become slimmer, it isn’t clear at all how it works or whether the results are even valid. You simply enter your height and weight (or even better, a fictional height and weight), and a result is produced. One other limitation is that users can weigh no less than 30 kg and be no taller than 2.5 m.

twtpets is a web app that allows users to vote and choose the “cutest pet”.

Features:

• simple web UI
• enter Twitter username, pet’s name and 140 character description
• upload pet’s photo
• easy click to vote for the “cutest pet”

The Good:

If you like battles between potentially cute pets, then twtpets is for you. You get to see lots of photos of dogs and cats, and get distracted.

The Not-so-Good:

twtpets is developed by twtapps, and unlike some of its other applications which are very useful (twtpoll, twtvite, twtTrip), twtpets is not. It is an amusing diversion, which is fine, but don’t look to it for anything other than that.

twitterlike is a web app that allows users to search themselves or others and display a “like-ability” score.

Features:

• web UI only requires you to enter a twitter username and click “search”
• “like-ability” score is generated as a percentage
• displays username’s following/followers/updates numbers

The Good:

Well, let’s see, if you need to know how likeable you are (or someone else is), then twitterlike could be useful for you.

The Not-so-Good:

twitterlike says it produces a “like-ability” score based on the “balance” of your tweets, but it doesn’t explain how it arrives at that result. what does it all mean anyway? The good news is, you don’t have to enter your password.

Twoogie is a web app that allows users to tweet while pretending to be Doogie Howser, M.D.

Features:

• UI appears as ancient IBM monitor and typing in DOS
• view tweets
• post tweets

The Good:

If you are/were a fan of Doogie Howser, M.D., or if you want to take a trip back to the days of DOS, then Twoogie is the right application for you.

The Not-so-Good:

Where to begin? The only real appeal of Twoogie is for those half-dozen hard-core Doogie Howser, M.D. fans. Functionally, Twoogie didn’t work. We couldn’t get it to post a single tweet, despite hitting it several times with a hammer. We could view tweets, but only one at a time. Also, login with Twitter credentials is required and there is no stated privacy policy, which could be a concern, even for Doogie Howser, M.D. fans.

Twimbler is a web app that allows users to submit links via Twitter and then view then view them (and everyone else’s submitted links).

Features:

• all that is required is a Twitter account, no registration or password needed
• tweet your favorite links using special commands and they show up in Twimbler

The Good:

Twimbler is a tumblelog which cascades “favorited” links and a short description of them. If you enjoy being awash in seemingly randomly generated links, then Twimbler is for you.

The Not-so-Good:

Frankly, the utility of Twimbler is rather limited. There are no configuration or search features, so viewers are stuck with whatever happens along. For Twimbler to capture the links you want to “share” you have to tweet them using a specific command (example given is #log: http://twimbler.com OMG! I’m trying twimble! ftw.).

Pick of the Twitter is a web app that allows users to view specially selected tweets billed as “the cream of the crop”.

Features:

• website displays a half dozen recently “picked” tweets and links to picks from the current month
• RSS feed

The Good:

If you enjoy randomly dipping into the Twitter public timeline, then Pick of the Twitter will please you. If you want to accomplish anything else, then this app is not for you. The logo looks cool.

The Not-so-Good:

Pick of the Twitter isn’t really an “app”; it’s a “service”. No login is required. Visitors to the site are greeted with a half dozen tweets selected by a classified algorithm or magic, or both.

Much is made of the secret algorithm, and we’re sure somebody had to stay up late at least one night to work on it, but consider two of its recent “cream of the crop” picks:

1. lol;
2. <?xml version=”1.0″?> < SearchResults> < Success> true< /Success> < Latitude> 37.677011< /Latitude>< Longitude>-120.960477< /Longitude> < Method>Skyho …

Twitter Ratio is a web app that allows users to obtain their Twitter Follower-Friend ratio.

Features:

• login with Twitter credentials
• Twitter Follower-Friend ratio is produced along with witty comment
• alternate method by sending a reply to @tffratio

The Good:

Twitter Ratio will calculate your follower to friend ratio and provide you with a little commentary about what that ratio means. It is another way to measure popularity/influence on Twitter. The commentary is amusing.

The Not-so-Good:

No fancy algorithms here, just a simple arithmetic calculation. At the end of the day, we’re not sure how meaningful it all really is.

TweetValue is a web app that makes users feel insignificant by providing a dollar value for their Twitter profile.

Features:

• simple, elegant UI requiring users to enter only Twitter ID
• Ph.D.-level algorithm calculates a dollar value for Twitter profiles
• view the dollar value for highest valued tweeters
• made in Sweden

The Good:

If you need to know an arbitrary dollar value for your Twitter profile, then TweetValue is just the ticket for you.

The Not-so-Good:

Although TweetValue cleverly figures out a dollar value for your Twitter profile, it doesn’t tell you what to do with that valuation. For example, the value of @jasoncalcanis is $14,235. The value of @tweetwave is $150, which we find slightly irritating, considering the amount of work that we do. If you find any of this amusing, you can embed a “nifty” badge in your blog or website and show your visitors how little you are worth. Also, we would expect a Ph.D. to spell “algorithm” correctly; even one from Sweden.
