Yeah, there are definitely some ways to game it, but, I think it's the most resource demanding of all the other alternatives.

I mean, vote in a matter of seconds or be forced to wait out 5 to 10 minutes, the latter definitely requires more "patience".

What I was really after though is getting a more accurate representation of what people actually like. Most people don't want to waste their time sitting on pages that bore them, they're naturally drawn to the blogs that interest them.
