Wouldn't it be nice to check someone's reputation on ServerFault or SuperUser even if you're currently browsing StackOverflow?

So you could check, how active he/she is on other platform and browse his/her profile on the over there.

That's why I propose to implement a little badge in the profile page which shows the reputation on the other platforms.

A nice addon could be to see the reputation if you hover over link to user's profile right in a question.

So: What is your opinion about my proposal?
