Actually, no. But I can see why you would think that. I literally don't know the range of what is reasonable and what is not. Your comment is implicitly informative, though. Furthermore, if I was being boastful, I would probably not be hiding behind an anonymous account.

Boasting usually isn't done to make other people feel bad; it's to make the boaster feel good. This post could serve that purpose even anonymously. If people confirm that you indeed are being highly compensated, that could make you feel good about yourself.

Not that I think that was the intention.

Could you add estimates of the amount of time each site took you (in hours), not including time spent teaching yourself, but including all time spent writing code, corresponding with clients, etc.?

That would make it easier to compare.
