The Good:

tweetvisor is a great tool for managing multiple Twitter accounts. It allows you to view your timeline and friends timeline, make groups and perform searches and tag results. There are all kinds of tools in tweetvisor. Multiple account management is a big plus, but the ability to make groups of friends/followers is a huge bonus. Search topics can be made “hot topics” and tracked on an ongoing basis. Almost every feature of tweetvisor is configurable by the user. tweetvisor could well be “TweetDeck plus”. On top of all that, it is browser based, so you don’t have to worry about API limits.

The Not-so-Good:

tweetvisor is good, good, good, but if we could point out one thing on this side of the ledger it would be that there is almost too much jammed into the UI. All kinds of useful information is tucked away as you access features. It just felt a little “cramped”. One other thing: it would be great to be able to schedule tweets for future posting. There.
