The irony in this post kills me. As 'parktheredcar' mentioned, there is no 'blogroll' (or 'link love', as he calls it) on the site, and the first thing that happened to me when I went to the site was an annoying subscribe pop-up. That alone is the exact answer to why this problem exists. As others have mentioned, people are far too greedy and want all the traffic to themselves. You are never going to get back to a linking web when, at the end of the day, you are just losing "customers".
Interesting. I actually still see lots of posts that have lots of links throughout the article. Especially when an article is referencing other code, projects, plugins, articles, etc. I assumed you meant more about the death of 'blogrolls' that has occurred over the past few years because that IS what has died out, in my opinion (and for reasons I stated above).
