It annoyed me that the best suggestion was not at the top of the right-click menu. Most people don't like having to move their mouse more than needed. See picture for more clarification: http://dl.getdropbox.com/u/10047/atd.PNG
The style subsection demo retains a couple of errors after following the suggestions of ATD (though I guess if the person checking it is paying attention, they would notice and fix up the sentence).
AtD biases heavily against false positives. If it's too noisy, using it is more work than it's worth. I only flag a missing hyphen if P(WordB|WordA) > P(WordA-WordB).

The grammar subsection demo does not catch the missing hyphen in one-hit wonder (http://en.wikipedia.org/wiki/One-hit_wonder).
I'm loving it Raffi. I use it to check my HN posts.
