I can see that you joined a year ago but didn't gain much karma. That means that you're an old timer, but a lurker, who doesn't post or comment often.
nickb and other top 10 karma users define this community and they lead by example.
I joined just recently, because I somebody posted a story about my startup and I had to comment. But since that I've been posting stuff that people care about.
All this is visible by looking at the profile of the user, without knowing exact posting history. This is huge time saver for everybody involved.
