MikeAI - thanks... Its true, I do wish the best for everyone!
I would guess that there are 5-7 guys doing $30 mil / year gross but that the top 2-3 are doing WAAYYYY more than $30 mil (as in 9 figures).
Net wise I would guess that the same 5-7 are doing $5 mil / year but again some are doing 4-5 multiples of that...
I would think counting all revenues spent in this business there might be 1 billion in gross receipts in this biz (not including inter market spending, if that is a real econ term). In other words, that 1 billion is NEW money, not money going towards the expense of that 1 billion (processing fees, commissions, hosting, content, etc...).
But, what the hell do I know...

Its all a guessing game for us, guess that is what makes it fun!
