Reddit, how you may know, is very popular social news site and Peteris Krumins did great job by creating RedditRiver – Reddit version for mobile phones. How he is saying he made RedditRiver because he wanted to make easier to read upcoming news from home or university. I think the idea of Peteris will be very helpful for other users too because it’s working great and may be quick solution to satisfy your hungry for news.
Speaking about usability it discovers mobile version of published stories to try to save your expensive mobile megabytes. For example YouTube videos will be redirected to YouTube Mobile and so on. It is also 3 times less in wight comparing to Reddit it self so I think your mobile company isn’t happy at all.
