Broadcast accounts include Facebook, Twitter, et al by default

First a "bug", then my suggestion.

Most of the services listed (those that I can identify, e.g. Facebook, Twitter, Digg, Foursquare) are hostile to freedom and privacy or do not run free software afaik, so I think they should be excluded from the list. And perhaps replace those options with social networks running only free software.

In addition, I would not create an account with any of those listed (identi.ca being an exception, but I think sign ups are closed this time). So to keep it useful, perhaps we could add a form that the user can fill out to designate a server of their choosing, for accounts not listed in the dropdown box.
