You know I've never gone out to just copy other features, and I'm not gonna start any time soon[]/w3timages/icons/wink.gif[/]. The actual idea came from rgranger. He actually did the the database testing on the performance increase by adding a timestamp to the query, and he setup his forums to allow this to be toggled and saved it in a cookie. I don't like to put too much into cookies as you run into limitations so I put it into the user profile. So, don't worry about copying. I still get all of my ideas from you guys.
So, with that. Remember, this is a new feature. GIve it some time, and more people may come up with their own ideas on how it works or how to make it work better.
