True, I always throw a few euro at Wikipedia when it needs some, and I regularly fund the open source software I use (like Krita).
I'd be curious to know if there are any data on how many people on average would donate to support something they deem valuable vs people who don't.
I mean, this is not a project started for profit, but if a significant chunk of reddit migrates here, it could get a pretty penny just out of donations, I think.
