Transfer Files using Bump

That would account for "100 million downloads!" but not actual active users.
Just now it said "Network unavailable" while I was connected to WiFi. It found a network when I turned off WiFi, but still failed to Bump.
Uninstall.
I could never get it to bump with my desktop (it's easier to just transfer the files through a network share).
I have literally never heard of the thing, let alone see somebody using it.
Just installed it again to see the mobile to pc bump, and although the web app picked the device, my phone never got a confirmation. Considering I still have to download the pictures from their servers, Google+ instant upload does a pretty nice job in this department. Until NFC.
My point in pushing NFC over Bump is that it achieves all of what Bump is trying to without relying on an external service or data connection. It's beauty is its simplicity and relatively low friction to use it for impromptu data connections, especially with strangers and people you just met.
Edit. Auto correct typo
