Are blogs and Microsoft related sites what you want to search?
Google is making it easier to find the things you want with some specialized, targeted, search engines. If you want to look in the blogsphere for some tidbit of info and you can't remember who said it, check out http://blogsearch.google.com - a new blog search engine.
If you're working on some thorny issue involving Microsoft technology and need to know something without cluttering up the screen with irrelevant hits, check out http://www.google.com/microsoft for an engine that searchs www.microsoft.com AND all the related sites (for example, www.eweek.com, compnetworking.about.com, and www.ebpml.org popped up as the top 3 results for a search on Indigo)
