So I saw that Michael Howard commented on a post I made last night... only, it isn't really him. Who is it? I'm not sure. But it does remind me that we need good identity management for weblogs. Perhaps we need it for the web in general, although efforts on that scale are hard to get traction. What are your thoughts on how we should manage identities for weblog posting and commenting? Given the success of the community in building on a few standards, what do you see as the barriers to this standard?
