Description: A very nice and easy to use HTML validator. You can drag and drop your HTML documents on this and it returns you a very thorough list of the errors in the HTML in plain english, even tells you exactly which tags conspire to make the error! (as in when you have overlapping tags, it will tell you exactly which ones, and so forth)
