Results in SO Careers for employers should have sorting by reputation.
I was against this, but employers kept asking for it, so I eventually relented.
Employers can search by reputation as of a while ago.
I disagree - what about a student (or professional) who just found out about SO a month ago?
If you sort by rep alone, you could be excluding new users just because they're new.
Reputation is merely ONE indicator of a candidate - you still need to look at their profile, what questions they've answered and asked, etc.
