Bang with friends seems crass... Not to mention randomly fucking your friends is usually a stupid idea. It makes social relationships awkward and complicated.
IIRC from reading about it, you just tick a checkbox next to all of the friends you'd like to bang; if one of them is using the app and ticks your as well then you're both sent a message. Presumably then a really awkward conversation occurs.
Also I don't think the kind of people who use an app like this are going to be aware of the fact that banging friends leads to less friends and weirder connections.
I don't use ios for couple of years now, can anyone tell me what happens to apps installed in user's device once its removed from the app store?
As a matter of fact, I don't know what happens when an app gets removed from play store either, does it happen often, what happens to the installed apps?
so upon further thought, if Zynga could trademark apps with the phrase "with friends", could someone like Marco Arment have trademarked apps that start with "insta-"?
