Yup

1) I don't get it, so I'm unlikely to think it's brilliant without trying. (So now I need a laptop to upload photos from my mobile?...)

2) I wouldn't download this to try Bump without some better explanation, especially given implicit data protection reputation of just about every big consumer-facing company these days (especially one that trades in contact details.)

3) The title is full of gratuitous editorialization, which is against HN guidelines.

I'm just viewing this as a proof of concept. If this works for uploading photos then it could work for anything tieing a bump profile to a website. For example now people use facebook to login to various sites. What if you could just bump your phone on spacebar to login or signup for an account on any site which uses their api even if you have not visited that site before, and provide them with information you selected on your phone. Could even be used for additional login verification of sorts. Sounds pretty cool and at least remotely brilliant to me.
