I'd go over and have a chat with them guys in the blogging forum, because they know more about this stuff than I do! (I'm not really one for the blogs!) But the online-webcams.com site seems to me to be a little wasted with a blog type site, anyway.
With what you were saying about high page rank and traffic ratios, do you understand how page rank works. It is nothing to do with traffic... You could have a PR of 10, but 0 traffic, have a look at this article on page rank,
PageRank. Just because there is a high PR, doesn't mean to say that you will have high traffic.
