According to Rich Skrenta, CEO of topix.net, Topix.net started by crawling about a million blogs, and then began automatically filtering and ranking these while considering a variety of factors, such as blog posting frequency, writing style, type of reference, popularity, and so forth.
What we're seeing is that 85-90% of the daily posts hitting ping services such as weblogs.com are spam (take a look for yourself). Of well-ranked non-spam blogs that we've discovered, we've found about half haven't been updated in the past 60 days. Our filters sift through what's left, which even after discarding 95%, is still a great deal of good material.Incase your blog is not included in Topix, click here add your blog to Topix.net. Topix will continually add more sources and their goal is to push toward automated coverage of I million news sources.
