The Register: Google to fix blog noise problem

The Register has a story which reports that Google is going to take blogs out of the regular search results and put them in their own tab in it's interface. My question is how they will determine what is a blog and what isn't? I mean, if the only rule is that content is regularly updated then that would cover just about any news source. Meanwhile, if they look at just highly linked systems, that could do away with some very pertinent results to a search as well. I'm excited to see what this ends up looking like.

Google is to create a search tool specifically for weblogs, most likely giving material generated by the self-publishing tools its own tab. CEO Eric Schmidt made the announcement on Monday, at the JP Morgan Technology and Telecom conference. 'Soon the company will also offer a service for searching Web logs, known as "blogs,"' reported Reuters. It isn't clear if weblogs will be removed from the main search results, but precedent suggests they will be. After Google acquired Usenet groups from Deja.com, it developed a unique user interface and a refined search engine, and removed the groups from the main index. After a sticky start, Usenet veterans welcomed the new interface. Google recently acquired Blogger, and sources suggest this is the most likely option.
