People who spend their time to post wiki pages, make edits etc never get any money.
Wikimedia is already earning good enough money via donations for their operating cost.
Whether they're putting the donated money to good use can be assessed from their financial reports.
This objection is the easiest to refute; all we need is to demonstrate the quantitative aspects of our willingness to donate, and this is what this post is mostly about.
Can you ask them to qualify how much exactly makes it "worth the trouble"? Once you have a specific target amount, and escrow, I will willingly donate $50 to this cause.
I don't think they should be bothered before we have at least $10K worth (100 BTC at current rates), preferably much more. Do you need them to quote a number? If so, why?
In the arrangement I suggested every treasurer acts as an "escrow". No qualifications are required other than being trustworthy. Do you mean there are some specific people you wish will be treasurers?
