No magic here, just plain old text search over content picked from feeds and syndicated back as feeds. The same old “search that doesn’t get in your way” UI design.
Search results are available as RSS (2.0), though that part didn’t make it to the UI.
But who moved my tags?
Update 1: [According to Scoble](http://radio.weblogs.com/0001011/2005/09/14.html), Google has less spam then Technorati.
Update 2: [According to Peter](http://blog.forret.com/blog/2005/09/blog-search-engine-frenzy.html), Technorati got their performance act together. At least their feeds seem to be updating as fast as Google.
Anyone knows whether Google is listening to pings or just spidering blogs as they do for regular search?
