The incredible shrinking main navigation

Recently someone mentioned to me the main navigation on cnn.com. I've read that site every day for about 6 years, but I couldn't tell you what even one of the main navigation items was. Lorem? Ipsum? No idea. What's interesting about this to me is that it was never a conscious decision on my part. I never realized that I never used it - I just didn't because, apparently, I didn't need it.

Now that I'm paying more attention, I'm noticing all kinds of creative ways that online publishing sites are de-emphasizing main navigation in favor of robust and well-designed homepages, user-driven navigation, and tag linking techniques. In this blog entry I share a few of these different techniques.
