Monitter
Monitter is a real-time tracking tool for Twitter. You can search for multiple keywords at a time. The web based application constantly refreshes to show any new tweets based on the keywords entered.

You can use this tool for vanity watching (ego surfing!), networking, or just doing research on a particular topic.
Additional features include an RSS feed for the keywords you’re tracking, and widgets (jQuery based) that you can add to your website.
Traffic rankings are sourced from multiple sources, if available, for the Twitter application. This includes Alexa, and Compete rankings.
