Plugshare's parent, Xitori http://www.xitori.com has been acquired by Recargo http://www.recargo.com
The two will continue to focus on software development related to EVs, and for now, the two apps will continue to be available. My own experience has been that Plugshare's is very accurate and tends - at least in Southern California - to include dealer site's whereas Recargo's doesn't. That said, it doesn't hurt to have both, and in any event, they're free.
