This is a curious phenomena that I've been meaning to ask about.

I see a lot of posts with bitcoin addresses in the signature, as if to say, "If you like what I say, give me some money."  And now here you are explicitly and directly asking for a donation so you can buy something for yourself.

How much bitcoin is being passed around this way?

I'm not criticizing.  I just find this odd and I wonder if there's a point of view I haven't considered.
