It's nice, that with Lybrum you are not forced into a linear reading book club but you can discover comments and thoughts of fellow readers chapter by chapter. Therefore you can read in your own pace and don't have to force yourself to read faster or slower than you usually would to stick with the same pace as the other readers.

Really awesome concept even if I'm not sure what will happen to the classical desktop in that idea (could be a frame as well).
