Earlier in beta there used to be option to share the question on social/networking site, but now it has been removed. Is it intentional or are there any plans to reintroduce it later on.
The options are still there if the question has no answer, but disappears once there's at least one answer. This is true for all sites including Stack Overflow.
This has been asked before on http://meta.stackoverflow.com (I can't find the link right now), and Jeff said that it wasn't going to happen for the existing sites.
