Sorry to see this site go. I've had nothing but a great experience. I admit I was a little worried when the site was down around the same time mtgox disappeared. But they came back, all my funds were intact, withdrawals processed no problems. Now I have three questions:
1. What other book should I use now?
2. Will we ever hear a reason for the shut down?
3. Would bitbook ever consider selling the site and/or application if someone wanted to continue it?
