Have I ever mentioned that we need a mascot for the forum? Kind of like how Uncle Sam represents the American government.
Coming from 4chan, I've been disappointed that there's very little fanart for bitcointalk.org. (Though it's not surprising, since 4chan is an imageboard and this is a text-focused BBS-type forum.)
If I'm not mistaken, there was a bounty looking for suggestions to promote Bitcoin. Both in bitcointalk and in /r/bitcoin. It could have a contest to select a mascot and then print stickers. 100,000 stickers cost less than 1Btc on this
site. Probably must have other sites that offer an even lower cost, the difficulty could be the distribution, though... And I imagine that similar suggestions have been made before.
The Bitcoin symbol already attracts a lot of attention when we come across it in some unexpected places.
