I just wanted to clarify one egregious point of yours. @crypto.piotr is NOT "helping himself only." In fact, he's working to build a strong, vibrant, and long-lived community that produces high-quality content.

And he's NOT "one helluva annoying salesman." Actually, the last time we met (last Sunday), I told him that, in a way, he seemed like a good salesman. I emphasized that adjective "good," because he was the kind of salesman that I would listen to and whose client I would gladly become. (And believe me, I HATE most salesmen, too.)

With Piotr, there was no sweet-talking, no exaggeration, no BS. Just an excellent, solid presentation of facts that convinced me that his project was well worth supporting and well worth getting involved in.
