Finally is all I can say its good that Wikimedia is now accepting Bitcoin donations not just for their T-shirt swag.
All I can really say about that is that first it was the store but now they are starting to use it for more purposes

Also wikipedia is definitely a site I would support so much data sometimes a bit off but that's what sourcing is for its a great starting point.
