I like 'em on avatars.
Otherwise, well, let's just say that if you saw me with a beard, you could pull it off.

(Now if I had a furred beany, the right specs,
and a white robe with blue stripes,
I might try growing a beard...
though I'd have to dye it brown)
And for others, no opinion one way or the other.
Colleagues often grow them some times, sometimes shave them off, usually to just try something different for a while.
I get the impression that wives generally don't care for them. They can make intimacy quite uncomfortable.
If you want to sing the Lumberjack Song properly, though, you definitely need a beard!
