They should focus their efforts on redditgifts (http://redditgifts.com/) and consider putting it on the main site instead of on a separate domain. Their users may not like to buy mainstream products but they definitely like to buy quirky, off-the-wall things as evidenced by `Shut Up And Take My Money`'s success with advertising on Reddit. They've already got the right idea with the marketplace model. They should (if they're not already) focus on trying to attract unique products through a program similar to Steam's Greenlight and stop focusing so much on advertising. Advertising and Redditors -- generally speaking -- are not a good match.
