I’ve always liked the idea of Bump: instead of trading contact details with someone by typing it all in, why not just pull out your iPhone and bump them together and have all the relevant details automagically traded between devices?
In reality, Bump’s main problem is that Apple hasn’t bought them and baked them into the core of iOS. I have Bump on my iPhone, but it’s not often I meet anyone else with it, which means I can count on one hand the number of times I’ve been able to trade contact info with someone with a totally awesome fist bump.
Still, if you hang out with more Bump-centric circles than I, you may well want to know that the latest update added the ability to add a Bumpee as a social network contact on Twitter or Facebook.
