Weighing in against, mk, for a slightly different reason. I don't follow people for their commenting ability (because until now that hasn't had anything to do with following) -- I just look at what they post. So there might be a user whose opinions and comments I respect a lot, but I don't follow because they share a ton of stuff I don't care too much about. So suddenly I have to follow him/her in order to get the comments at the top, and I potentially sacrifice the "integrity" of my feed. Not a huge deal, but maybe something to consider. Following for comments and following for posts don't equate at the moment, necessarily, so if you implement a policy that assumes they do it may not work well. So unless I read this too quickly, I'm against this for the reason outlined above. I may be jumping to conclusions; I'm at a meeting.

Indeed, reasons for following are many. I follow to build self-esteem (but don't tell that to the people I follow).
