You could have a P2F app or an AgentInBox app or an app so people can give/receive feedback on their writing. It doesn't have to be the whole site.
If I use my mobile browser to visit WeBook, I get all sorts of problems. I can't open chapters, so I can't read other peoples work and I can't comment on their work. I can't see what other people have posted on my work (I can't open the chapter). I can't post on the forum or ask for support. The website doesn't work. The browsers I use on my mobile are Safari or Google.
Surely by 2015 we should have something that works on the go...
