Some are just in general. I like to try new apps but if they're too complicated, even if they have help pages, I give up. The new read it app, I didn't know anything about what the app did because I never used redditt. I had to go to Wikipedia to read about redditts. I don't have much experience with Social apps so I have to go to the internet to read about the terminology that's assumed the user already knows. I get Skype, but for the life of me, there are things I can't figure out how to do on the phone version, Rt or computer.
