A suggestion to improve acceptance from EFF/wikipedia/whoever..
The bitcoin foundation should establish individual donation addresses, each associated with a large organisation people are interested in donating bitcoins to, eg:
Wikipedia 17qq5A3XKfrxpJRSC5LH6APjvTDb9hTms
EFF 3e4frt588gdwo844t93hg8943h9348hg984g8
etc..
Donations are made by bitcoin holders to these addresses with a date of return if the organisation persists in not accepting bitcoin. If they do decide to accept bitcoin, the bitcoin foundation hands over the wallet.dat file, and the organisation gets to keep the bitcoins.
If they do not accept bitcoins by a certain date, all donations are returned to the original addresses from which they were donated.
Having $100k in donations sitting in a wallet file staring at you is much more likely to encourage acceptance than nagging and email bombs I think.. kind of like positive blackmail
I don't think this is a bad idea at all but I ultimately believe that bitcion wil reign supreme at the end of the day so those slow adopters do so at their own loss. I'm not going to pester anyone into accepting it. If it never grew more than the level it is now I would be perfectly happy. It serves my needs fine - I can buy gold and I can buy national currencies with it. With those I can buy anything else.
