I have my website use YQL to go into http://freerice.com, pull members of my group, and then go into their page and use YQL again to pull their stats. I also use it to pull how much money my Relay for Life team has raised. I am actively integrating YQL as much as possible into my site. It is really helpful because I can't do any server-side scripting, so YQL is the perfect solution. My website is http://helpinghuskyobjective.weebly.com.
Why would you ask for cool sites when folks are having so many problems with your tables. PLEASE address the seemingly hundreds of requests about "TABLE IS CURRENTLY BLOCKED".
You don't seem to be listening to your users. Your tables are timing out based on globals calls on not individual calls. PLEASE FIX THE PROBLEMS, or don't ask for cools sites because it COOL site infers that it is a 24/7 up and running site.
