antisocial network Your Turn Rename ﬂips.timestamp

I’m afraid I have some bad news… antisocial network

Antisocial Networking Startup Flipr Heads To The Deadpool by Michael Arrington on July 19, 2010 I loved this site. Flipr, an online “antisocial networking” site that encouraged users to alienate each other in order to increase their antisocial cred, is shutting down. The antisocial network startup’s homepage now consists of a letter to Flipr users instructing them to download their “ﬂips” by July 31, at which point nearly all of the service’s features will be taken offline and data deleted. In the letter, Flipr CEO David Wheeler writes that despite ample venture funding and a dedicated team of database developers, the site underestimated people’s willingness to be assholes. This is not something I can relate to, although from what I’ve been told by more polite society, it is indeed the case. Such a shame.

I’m afraid it’s true. RIP antisocial network

I’m sorry I have no money left to pay you. RIP antisocial network

I hope you enjoyed working here. RIP antisocial network

And that you’re able to use the skills you’ve gained in your next job. RIP antisocial network

Good luck out there. RIP antisocial network
