More, I like to read and once I start to read a good story, it is hard to stop, so them curating helps a great deal.

It is not that great with SF, it is more my heroic efforts that found some SF to be read. I hope they will use money to get more.

Also, I would say, some social aspects where you can discuss books you want to read or just read, would be nice. I am member of goodreads and frankly, I am tempted by promise of them being integrated into newer kindles. I have rather old one (like a year or two :) )
