Thanks for your input @ilyastarar. I have worked using busy since February and it has only improved. At first I like the way they made markdown accessible. Later I liked the voting slider they gave me even though I didn't have 500SP. Finally I liked the notifications. I could figure out who was following me quickly and who was interacting with my posts without having to go far.

I have experienced only one problem with busy. I write something and then click on a link and lose what I was writing. This has happened several times. Sometimes the drafts are backed up and sometimes they are not. Is there a general rule for saving drafts?
