Ed, how about giving ABers the opportunity to dislike/like an answer by offering them the chance to hit a red arrow for dislike and a green one for like. JD
"here" being ChatterBank, not the entirety of the site; everywhere else it's likely to be used as intended. It'll definitely be useful for picking out popular threads to feature, and we'd probably exclude CB from these features anyway.
"... and will you know who has clicked either a ^ or v ?"
Maybe, would give some accountability if it was public. Could have another tab in public profiles for things you've "arrowed". It'll certainly be recorded in the back end so if someone is "maliciously arrowing" we could discount them or something.
"lol... does any of this really matter?"
Of course not. But if it were to happen it would become important.
