Thanks for your comments. I agree with your comment about the true randomness (although it is nice to explore all parts of Wikipedia, and the randomize button helps in exploring), and we are actually working on adding categories. The problem is that Wikipedia doesn't offer any helpful API in doing that, which means we'll have to download and analyse (on our server) the Wikipedia db for all the languages we support, which is a bit of a PITA. Btw, a nice feature of the push aspect, is that we only show articles when unlocking the screen so they don't interfere too much.
