I like facebook, but I also like to quit periodically because I find it distracting when I need to get work done, and frankly, my fb friends, god bless 'em, can get annoying as hell sometimes in aggregate. Even if we leave aside the debate on the pros and cons of anonymity, there are a lot of legitimate reasons why people wouldn't want to use facebook as a web-wide identity platform. Creating a forced dependency for something as basic as blog comments on a site otherwise unconnected with facebook seems very dismissive of people's preferences in this area. Hope it doesn't catch on :-/
