I really like to see the profile of the users who answer my questions if they have a lot of rep, because I might learn from a question that they asked or answered.
I see a lot of users who received rep on off-topic questions kept for historical reasons. like this
This question (and many others) has given a lot of rep to the asker and those who answer.
It might be unfair to remove rep from those guys, but questions before were easy to answer. Nowadays, it's harder for new users to get rep. So is there any way to make it a fair game for new users without making the old users angry?
