If this was my site, I would make it a members only site. Have some free stuff as teaser copy, but make people pay a subscription $100/$200 a year or $20 a month or something like that.
Cut down the ads to a bare minimum and offer all your products as pdf's and podcasts to members.
It's ironic that you would call them your 'future' plans, when you clearly only believe in the moment,
which of course is the only really logic approach.
I'd join if it was a subscription site, then I wouldn't feel guilty about not donating.
