When I log in this morning (to WordPress) I notice alot of feeds about Google Blog Search. The first thing that comes to mind is that Google is adding another button in their searches (Like the web, feeling lucky, and image), but no, it is a whole new feature from Google. As if Gmail, Google Talk, Google Maps, Google Desktop, Google Suggest, and the other countless features weren't enough. I don't see why Google couldn't add this as an extra feature on their search engine, why another BETA release? Show me one feature that has gone out of BETA.
Other than that, let me tell some of you who haven't heard what it does exactly what it does. It searches blogs, just blogs, and nothing else. When Googlebots are crawling over the WWW, it reads your meta data and goes through your RSS and Atom feeds, if it identifies your site as a blog, it indexes the information it finds and puts it into the blog search database. This is all done from your feed data. That's it. Not really an amazing feature, all it really is is a huge aggregator with a search feature.
