Although Patreon is nice, it seems to be more focused on artists and the like. A similar project focused on Open Source Software is Bounty Source Salt (https://salt.bountysource.com/)
> Is a piece of software not art? Are its creator/creators not artists, expressing their vision?
Indeed this can happen (though not always - I, for example would not describe, say, some business applications as "art"). But nevertheless the markets for art and software are IMHO rather different, so I would be cautious when lumping these two markets together.
