How it works: Once you sign-up, you download the add-on (available for Chrome and Firefox), and start using Comment To. It's really simple to use, all you do is: Select, Comment and Save. Comment To solves two problems: bookmark/excerpt and comment. Say, I'm reading a book, and find something interesting that I want to remember, now I'll put a bookmark there. Forward a few days, and I come back to the bookmarked page, and now I have no clue what was so important on that page.
