I sometimes have the impression that people are just adding a wiki blurb to a tag to add some reputation the easy way. The tags in question have no followers.
I don't feel comfortable with having dozens of tags that are almost the same and could be put into some common tag. E.g. there is no need to have a tag per Android-view or widget.
I wonder if SO could just not allow to create the tag wiki if e.g. a tag has less then 5 followers or less than x posts.
Otherwise: how do other moderators handle this?
