i have made it a point to NEVER, EVER think you know a person or his credentials by the way he is dressed or the way he looks or even the way he talks and acts.
You will end up getting embarrassed. Thanks for this Post @cryptopie
P.S. I can remember when I first joined here. For a number of months I had only 60 SP. And I can say there was a few people who wouldn't give me the time of day. Once I got over 1,000 SP it changed a little. But those people who dissed me when I was at 60 SP I still have nothing to do with them.
