It is true, I don't know what kind of concrete benefit would come from it, but I think it could help people navigate the social groups and get a better feeling for who is who, how they moderate their posts, and what types of posts they're likely to share. The profile already shows users we follow, for that purpose, I assume. For example, if a person is sharing a bunch of pro-GMO articles and has a bunch of anti-GMO contributors blocked, I might want to avoid (or seek out, depending on who's who) following that person and engaging in their posts. With the current tools, I don't think there's any way to do it. I suppose it could be used as some sort of "burn book" but I don't think there is any shame in blocking people you don't want contact with. Let it be open and honest, though, so users can see and navigate the social web.
