Funny you should mention that place...
I love their average cheatsheet. Now they have expanded it from 10 to 18 sources! I also noticed that it died on me when I was trying to show a friend at work. I have no idea what happened. Maybe it couldn't pay for its hosting, or maybe the places it was taking the rankings for told them to shut it down (giving away info you have to pay for for free)?
I just hope it hasn't gone the way of the Seraph (although we keep hoping it comes back)! That would be a big loss for me.
Edit - as of the time of this post, it was back up. Hooray Beer!
