I seriously wouldn't worry about HTML validation. Not sure what prompted him to even check. It's a waste of your time. One of the biggest things I've learned from startups is that you shouldn't take every suggestion and spend time on it or assume your product sucks.

In that spirit, here's a suggestion: if you have some examples of things you've done to put in each box, I think that would help. I might be contacting you!

Good luck!
