If you're going to list 'big' sites anyway (a subjective concept surely), pity you didn't mention Sims 3 Uploads, which dwarfed MS3B as it wasn't as easily intimidated by self-appointment hipsters from the less savoury side of the Simming community. In your own list My Sims 3 Blog ceased updating last year, Ace Creators two years ago, etc, etc, so with respect you don't appear to have researched your own list to make sure they are still operating and the links valid.
