That's a good point. It's set up so folks can edit their tweet, hopefully making it more relevant to more of their folks, but how many followers will really be in SF or the Bay Area?
A motivation for sites like sfmayorvote.com is that Twitter (and maybe Facebook statuses) potentially offer a new way to measure and visualize public opinion. That's a goal that has huge implications for democratic governance, marketing, etc.
But I'd say Twitter has some design flaws that really limit its usefulness there: for instance, the fact that you can't have both public and protected Tweets on the same account, and the fact that it's not easy to be selective with who receives your Tweet. I'd love to see the Twitter folks add good functionality to address those issues.
Hey Josh, what if I want to turn my head to the right to look at my pair? One of the things I need ergonomically is to even out the twists in my spine. Seems at a place like Pivotal you might want to encourage people to do the same.
