Just for the sake of argument let's say it's way less, say...40,000 active users. Then, let's say that a measly 5 percent (2000) of them were willing to be regular monthly donors. Keeping this hypothetical scenario going, assume that each of them could only donate $15/month (50¢/day). That would still bring in $90,000 per quarter, and there would be no need for FReepathons.
That wouldn't make us fat, but it sure would relieve the pressure. Praying that more FReepers will join in.
