Congratulations, Wikipedia! I found it tremendously useful over the years. I have one suggestion for them. I wouldn't mind making micro-donations for articles of particular quality and relevance to me. Say I find something useful and click on a '2c' donation button. The system doesn't trigger an immediate payment transaction because I would not have time to do it but instead waits until I accumulate $1+ in 'spend' and then displays another button 'Pay'. This way micropayments are easy for me as the reader and at the same time Wikipedia's transaction costs are minimized. Besides, I like to be able to pay later.
