Re: 1150: Instagram

The deal with Instagram was that, due to the way the internet operates, you have to allow them to serve photos you upload to people who request to view them. If they aren't allowed to do this, the service is pretty pointless. They've always said this is a non-exclusive right - you can always put you...

Re: 1072: " Seventies"

Re: 0979: "Wisdom of the Ancients"

I just realized how old this problem is.
