YackTrack shows you all the places people are commenting
YackTrack is just getting started, so new features are rolling out quickly. There's already a bookmarklet you can use to avoid unnecessary copying and pasting, and a FeedFlare you can use to track a given URL. On top of that, YackTrack features a "chatter" search, so you can see what people around the web are saying about any given search term. I tested it out with my name, and it looks like a fantastic ego-surfing tool. It's probably even more useful if you're in customer relations and want to track what people are saying about your product and service. You can even subscribe to the search results as an RSS feed.
