Search Twitter Topics at Monitter

Simple. It’s a twitter monitor, it lets you “monitter” the twitter world for a set of 3 keywords and watch what people are saying. It also enables filter entries for its location and also by language in which they are published. It also adds a direct link to an RSS feed that Twitter makes available for each of the terms sought.

And if that were not enough, you can put a wigdet with the results on your website. The Widget is easy to install, and should be useful to those who like to have a twitter follower display new content through their blog.
