Numbers shown right now are 546 patrons and $1227/month. That's average $2.25/patron, you don't have to be very rich for that.
Also the recurring assumption that supporters are dumb in some way, either to realize that they get cheated, or just dumb in general, why so many people think that? I'm a patron of his myself, I give him whole $1/month (yes, I'm cheap) and I know very well why. I'm no victim, I know what I'm doing. He made something nice I liked, I decided to send him a small "thanks". That's fair. I keep it going for a while, and it's up to him what happens next. If he continues to provide nice things, I'll be more happy and I can go up. If he doesn't, I stop when I feel that my "thanks" is big enough. No hard feelings. Where do you see any problem?
