From my feed:

Oh that is interesting. New Share function in G+! When in any Google page and if you are logged in, there’s a box called Share in the upper right between your G+ profile pic and your G+ notifs. Clicking on it opens the normal Google share/status update box. This is intreresting.

I think this was one of the backend visual improvements Joseph Smarr was talking about the other day. Will update more when I get the time.
