There are several things they could do... I would like to be able to bring up a list of posts by primary tag; then sort THAT list by number of comments (level of engagement) or by writer's rep, or some other metric. None of these things are particularly hard to code...

I would love to have a "delete" function for followers... some variation of how Facebook works; you have to "accept" a friends request. It would enable me to get rid of the estimated 1000-1200 "shell account" and bot followers I have... and don't WANT.
