Does Sharekit still work?

When I try and use Facebook with Sharekit, it pops up the login dialog, I fill in my credentials and then it just disapears (it does this in the sample project as well) Am I doing something wrong? Or is Sharekit just defunked? If so, any viable alternatives?

Yes it does. And it gets better - there is a new repo on github, which aims to bring it alive again, from the flood of various forks.

I'm using ShareKit on a current project. The Facebook integration performs this way sometimes, but I don't think it has anything to do with the library. Remember that the Facebook dialog is hosted by Facebook. It may have to do with a temporary hiccup on their end.
