Former Google+ UX designer (and hashtag inventor) Chris Messina has declared Google's social network a bust in a scathing post on Medium. "What’s going on with Google+? Where is it headed? What the fuck is it for, anyway?" Messina writes, decrying Google+ for wasting its potential and becoming little more than a Facebook clone. The post comes in response to a tweet Messina fired out last week, in which he pointed out a Google+ bug that he wrongly interpreted as a sign of Google shuttering its social network.
