Or it could go the CS:GO route and run on money paid by the users in exchange for cosmetic bonuses. In this case, users can pimp out their username font, text color, vote icons, etc. Basically, make saidit cosmetically customizeable for small transactions that will help the site.

To keep the money rolling in, maybe make the uses limited. Like, $3 for 60 comments in green color, $5 for a colored username for 7 months.

If anyone here has ever used FunnyJunk, they have a similar system I thought was cool. It incentivized people to keep posting and showing off their swag. Some people can opt out of the colored text system if they get annoyed with the chaotic colors, but they will also give up being able to swag their own posts.
