TweetVolume is a web app that allows users to enter up to five keywords, click “Go” and display a bar chart in pastel colors showing you how many times the keyword is mentioned on Twitter.

Features:

• simple UI, allows up to five search terms
• send resulting graph to others via email

The Good:

If you want to know how many times a particular search term appears in Twitter, then TweetVolume is for you. It is easy to use and the graphical display is appealing.

The Not-so-Good:

This is a “cute” little application, but won’t be useful for those wanting hardcore trending information. There is no facility, for example, to designate a time frame within which the keyword(s) appear in twitter.
