Aside from the footer, I got a completely blank screen, even after reloading a few times. I think I figured it out: the site loaded fine after I enabled cookies for flowtown.com. I wish the site gave a warning that it requires cookies.
I just tried it, it worked on the 2nd click. Probably just Twitter API timeouts (as per usual).
I put my username in the first field but it kept on saying, "Oops, there was a problem".
