A “Friends List” on StackOverflow would be nice
It happened several times to me, that I gave an answer, that the asking user commented as very useful but is not even giving me an up-vote. Even after saying that an up-vote would be nice.
I'd like to keep track of those users. (i.e. this user, who got 28 answers on 17 question but has only 1 up-vote)
My idea: Mark users with the colors green, yellow or red, where green is for users I'd like to answer again, as they were very polite, while red is reserved for users, that really freaked me out, as they are never giving credit, where credit is due.
Users become "mark-able" as soon, as they can vote up.
Users can mark other users with a reputation of 100 or 200
The color will be show in the little box below their question (next to their accept rate).
