oddly, hardly anyone realizes that Ranker.com is actually one of the most successful semantic web plays...
They get 8+ million page views on a good week.
Other lame content theft sites like Mahalo have been practically put out of their misery.
Personally I've looked over the data for a number of successes and failures and I don't believe the conventional story about Panda.
Adding the data in this article to everything else I know about Ranker just confirms my model of what works and what doesn't.

and select page views, week, and global they still peak at 4mm. Which is nothing to laugh at.
