I suppose it would be inevitable that a site which promotes investment in Social Media companies would get so heavily involved in politics. If Reddit is a good example of the Vox populi, then the future we can look forward to is one of "VOTE UP IF YOU SUPPORT BILL 1780-1X". Mob rule, internet style, will be the future, given the proper backing by certain VC's and angel investors, of course.
Much, much better than SOPA.
