Google launched a blog search service. Exciting stuff! It's sparse and quick and it works decently enough. I like to keep tabs on who's linking to me, so I've subscribed to the search results for my site alongside my Technorati and IceRocket results. Google returns 80 results, Technorati returns "218 links from 157 sites" and IceRocket returns 106 results. I haven't done any research into the additional 26 links that IceRocket returns, but the way it displays its results is still my favorite, with the entries grouped by day.
