Update Mar 31 2014: Readmill has announced they will shut down. Sad, sad, sad news. Might have to go back to Kobo or find a new one.
I like to read once in a while and for a long time, I have been using Kobo. It works pretty OK. Neat UI, nice social media features, achievements to encourage you to read, and a nice widget. The only problem I have with it right now is it can't find the epub files on my phone. I'm not sure why. It could be the Android 4.4 KitKat ROM I am using since that's the only variable that changed since the last time it worked (was on an Android JB 4.3 ROM before that). Now how am I supposed to read my ebooks if it can't find it, no?
