I've had Android phones for a couple of years now (was it December 2010 that the original Droid came out?), have downloaded tons of apps, and not had a problem with any. I suppose I'm somewhat picky on what I install, and don't install ones with security permissions I don't understand. I suppose that's one of the nice things about this app - it alerts others who may not know better that some of the permissions may be shady.
