In other Google news, Google Reader added a nice little feature today for bloggers. You can turn your list of feeds, or any subset you choose to make public, into a blog roll. That will help spread Google Reader technology across the Web, and give Google another data point about blogs and feeds which could become another factor for it to consider in its blog search algorithm. Adding a blog to a public blogroll, after all, is an explicit endorsement from readers rather than from other bloggers (linkers). Of course, if Google did start factoring this into its blog search, it would be pretty easy to game—just create a ton of blogrolls with your blogs on them and start clicking away. Oh well.
