A fantastic way to find websites, blogs, pictures that you would not otherwise find easily or, in my case, even imagine. You do needed to spend time setting up your interest categories, then Stumble, then adjust the categories. Option to Stumble just one category is great. Interface is ok and not slow with wifi. I find it fun on my iPhone but suspect it would be better on an iPad. Content is richer than Beyonce (design focus) or Flipboard (social media origins). Beware, this is an App for adults. There is little censorship: "Babes" will show you women in bikinis etc but also porn sites. If you have wifi and half an hour to kill, you will have fun and probably learn something.
