Honestly can't think of them off the top of my head, and I can't bring myself to find them, I've gotten so many interesting comments over the years. A lot of really nice ones that would make you feel shy, good guesses about where the story is going, guesstimations on why certain characters are the way they are based on what they've talked about and flashbacks.
Some of the more interesting ones came from a discussion I got on my comic a few years ago on the Webcomics Garden server, I regret signing up for it so soon since you can only do it so many times. Another cool one was Comic Tea Party, a discontinued group that picked comics to talk about as a sort of review/open discussion. Unfortunately I can no longer access the archive to retrieve my entry.
