In case you had any doubt of Twitter’s powerful grip over the net, here’s yet another app designed with our favorite light comm app in mind:TweetVolume. Judging from the name, you could hedge your bets that TweetVolume has to do with numbers, and you’d be right. To be more precise, TweetVolume scans and counts the number of times a word or phrase appears on Twitter. You can type up to five terms per search. The results are displayed in a colorful and comparative bar graph. The bars represent all mentions of a word/term from Twitter’s inception until the present moment. And, of course this is only from public Twitter feeds. You can also send your search to a friend—more than that, remains to be seen.
