I've seen your Twitter feed--it's full of accolades. Congrats on a great app release.

I'm not picking nits with Writer, though. My problem is with the family of "zen apps" that help writers "get in the zone," including yours.

If someone is frequently distracted when they write, they either (a) need to get away from the internet when writing, or (b) reevaluate whether they enjoy writing. It's like the programmer that can't decide between Emacs, Vim, TextEdit, or other IDEs. Stop making excuses, pick something, and work.

The fact that people will buy this app because it'll finally help them write without distraction just...bothers me. Maybe because I was there before. Anyway, don't take it personally--your app is selling like gangbusters, and it looks like a great user experience.
