Thanks Jeff :) We have a lot in store for folks. It's really exciting work both on the front-end and the back-end. For folks who want to know the difference between AtD spell check and what their browser has, I recommend trying this sentence for a comparison:

Something to conoisur when talking to a wine conoisur.

Safari does grammar check but AtD is the only technology in the web space doing misused word detection and contextual spell checking.
