Personally, I love to have my websites reviewed, critiqued and graded. I also love collecting massive amounts of data and sitting down with a nice cup of coffee and reading through it, analyzing it, interpreting it, and ultimately using it to improve my online efforts. I recommend these efforts to anyone who wants to make their website better!
