Sharing to twitter also doesn't seem to work. I pressed the 'authorized to use' and that seemed to work, but after I authorize, it says 'you will be redirected back shortly', except it doesn't finish the redirect and because it doesn't finish the redirect, the authorization never finishes so looks like to twitter is not gonna work.
Ah well.
Anyway, while I've started this project, I've actually got some catching up to do elsewhere so I'mma gonna go do that stuff now.
