When I share a question, say to my facebook or twitter, it gets tracked by the site. (I know it must, otherwise you wouldn't be able to provide badges for successful shares!)
Would it be possible to get some feedback on those shares other than badges? If I know what shares were effective and what ones were largely ignored, it will give me better feedback to share most effectively. If I've put three questions on my Facebook about [topic-X] and they all only get 3 or 4 hits, while the three questions about [topic-Y] all got like 20 or 30 hits, I know that I should be more inclined to share [topic-Y]. But unless I get a badge for it, I don't know anything about it. Furthermore, those badges are only available once, so the long-term feedback provided isn't much.
I've only just started sharing posts, but I'm quite interested in getting this feedback so that I know how effective it is. I'm thinking it could be a tab in the userpage or something like that.
