Nice! I agree wholeheartedly. There's nothing to gain by perpetuating negativity other than looking like a shit head and bringing everyone down. I choose to ignore turd-like beings, lead by example, hope for the best, and keep truckin'.
But to answer the question at hand, one person that comes to mind is @acidyo. He's simply a solid person that doesn't play into drama, trashing people, etc. Dude is certainly perpetuating the greater good of community. Be it from spreading the wealth around to the best of his ability, to just being a positive influence/voice that will talk to any walk of life. He's just . . . a good community member. Someone that you want around, someone that you don't think to yourself "Gyah, wish this dude would lighten up," or "Man, this guy is being a downer, wish they'd talk to Ronald McDonald or something," about.
Looks like he has a decent amount of personal stake and a fat chunk of delegated stake.
I believe that about covers the bases though. Keep fightin' the good fight, Fuzz! I'm down with your cause and I hope others are as well. It's hard looking at a WWJD bracelet and really trying to live it. Most can't pull it off, but some strive to.

Wooooohooooo @acidyo -- just don't clone him please ;)
