Technorati has this new feature called Favorite Blogs, where they allow you to upload your blogroll and make it available as a reading list to others. Just one problem, it exposes the weakness of the Technorati index. Today, Technorati features four blog favorites. Each of these reading list has at least a few and some even a dozen blogs that haven't been indexed in days, weeks and months (one blog hasn't been indexed in more than a year), but that are updated daily by their authors. In fact, a handful of blogs aren't being indexed at all. Next time Technorati says they've indexed 28.4 million blogs, ask them how many have been indexed recently. It would appear to be substantially less.
