I met the founder of DailyLit.com three years ago and thought their idea was very cool. Subscribe to a book and have it delivered right into your inbox in digestible chapters. I think it's a great idea. However, if you zero out your inbox and get behind in the reading, it can be a little tough and I've abandoned a couple of times.
However, I just signed up for 'DailyLit's Big Read' which just launched and the first story was 'The Curious Case of Benjamin Button' – great timing to get in line with the Oscar's buzz, but just wonderful content for DailyLit. The wonderfully written short story by F. Scott Fitzgerald is just perfect for this type of consumption – and the best part about this title – its free.
One of the problems I thought about the email subscription was with something like 'The Art of War' – I can't remember what the number of emails required to read that was, but it was a lot and kind of depressing. Seeing (1 of 67) in your inbox subject line doesn't help your anxiety of your overflowing inbox.
Give it a try.
