i think the ADMin already gets more the $1 from each members per day in shape of contents and ads clicks and i still pay if they ask...
DP should be around $100/year to stop all them idiots from joining who think they know it all and tell you to go get more PR because Google penalises you when your PR leaks out.
Yes I would even pay $1 as a tax for the community. DP has taught me many things so $1 is really nothing
DP is #1 in google ranking now, because it is free. If it was paid, then, member will reduce dramatically, actually, new member will not interested. Except, I don't know current earning of DP, so I can't give actual opinion. No. of new member will reduce but 1$/each. So, comparing this two final judgement can be done.
Shawn is very secretive on the issue of income, however the rumor is that DP is one of the most important Google Adsense publishers
You haven't taken ANY advice we gave, learn to spell, there was huge thread about it and yet you still ignore it.
