I hate to pick on rk. because he is a good contributor, and I have seen a few other people engage in this behavior too.
But when I log onto this site, and see something like this, it bothers me because it pushes down other people's questions. I don't mind people doing benign badge-whoring, but I think this particular one is damaging to other people's threads.
Can we consider removing the badge for editing other people's posts? I'm sure there are other ways too. (e.g. limit edits/day. cap the top badge at bronze. etc)
EDIT: I'm not just referring to minor content edit. I'm also referring to Tag edits. It makes no sense that Tag edit results in thread getting bumped to the top.
