I'm sure we all know the story by now:
Unfortunately we do not accept bitcoin, however, we are aware of bitcoin and we will continue to monitor it with interest.
I'm genuinely curious, however, how much they might be missing out on by not taking Bitcoin donations in addition to PayPal, credit card, check, and other donation methods.
The minimum donation amount (provided you don't plug a smaller number into the "other" field,) is only 3 USD, while there is theoretically no limit to how much one can give them. My question to you, friends and enemies alike, is just how much you are willing to part with to help Wikipedia and the Wikimedia Foundation, were they accepting Bitcoin, either in local currency units or BTC.
ETA: Yes, I am aware of the option through Bitpay. This is valid as well, and amounts given/to be given through this are requested as well.
