As a long-time Redditor (see /u/habstinat) and avid follower of
/r/linux and /r/gnu, I think this could be a great idea. Recently I
tried to use Reddit to get people to design a logo for OpenPhoenux
(manufacturers of the once-Openmoko GTA04 "truly free" GNU/Linux
smartphones) and it was a huge success, getting to the top spot of
/r/linux <http://www.reddit.com/r/linux/comments/16fski/> and close to
the top of /r/picrequests, yeilding almost a dozen logo submissions,
most of which were very professional looking:
<http://www.openphoenux.org/logo/>. It also sparked some interest in
OpenPhoenux and I'm sure resulted in at least a few purchases.
To avoid the similar fate of /r/freeculture and the like, we need to
aggressively promote the subreddit in /r/newreddits, /r/linux, /r/gnu,
et al. I'd definitely be interested in helping you start this up /
moderate this.
