My favourite section is the one that sends me mails about "what are we reading". I don't always read it, but when I'm up to a new read, I get ideas from that. I found a starting author and some good books here!
Besides that, I found lots of information for my former e-reader, the i-rex. Unfortunately, the screen broke. So now mostly I read on my Nokia...
Keep up the good work!
Personally, I don't need any improvement. Maybe a little speed on the search engine, but that's all.
