I'll let it be known that I spend a lot of time on Reddit so I find it odd that people can't upvote their own questions. On Reddit, each link or discussion starts out with 1 point (that given to it by its creator). Is there a fear that people will try to create 100s of pointless questions so that they can get easy rep? I'd think that the downvoting by the community would make that pointless.
Just my two cents (for what its worth),
P.S. Humorously, this seems to be a 0/1 starting index argument.
