Do you understand why?
It seems as though the main gauge of Instagram is the number of times the app has been downloaded. I've downloaded the app, but I've never used it. I got hung up at the phase where you establish an account and connect it to Facebook so it can feed off my Facebook account. I just don't feel that good about that. Maybe that's just me.
Anyway, is Facebook just capturing a predator so its competitors won't use it to undercut Facebook? What's really going on?
