Warning: you might spend a lot of time on this site - but it might be worth it…

Blogs are often a valuable source of up-to-date information, but how do you find the good ones?

I got two emails from John Reese this week (more about the second one in a minute). John announced the launch of TrafficJam.com, which highlights the leading blog entries in his massive BlogRush network.

TrafficJam uses sophisticated technologies to analyse the click-through rates of millions of blog posts across the BlogRush network (and a few other factors), and then posts summaries of these entries.

You can look at specific categories of blogs, or do a search for keywords. It’s pretty powerful stuff, and you can see TrafficJam in action here:

Incidentally, if you’ve got a blog, you really should have the BlogRush widget installed on your blog. It’s free, but your blog has to meet certain quality guidelines. Read more about it on my “Marketing Sparks” blog post here:
