Mathew Ingram notes a CNet story that links mostly to itself, and then ponders whether it means the end of "the link economy"

This is an issue that comes up periodically (one of the last ones to bring it up was Tim O’Reilly, in a great post). It’s fueled by the desire on the part of sites like CNET to prove how authoritative they are by making it look as though the only stories worth linking to are their own. I have nothing against CNET as a news site, and I think Caroline does some fine blogging, but to say that their internal links are better than anything else they could possibly link to is just ridiculous. It’s obvious that they either didn’t even bother to look for other information to link to, or there’s an internal policy to promote their own material. Both of those things are wrong.

He goes on to note that this behavior is rampant in the MSM (Mainstream Media), and we don't really need it elsewhere. CNet was bought by CBS recently, though - doesn't that make them part of the MSM now? Rather than this being some kind of trend, isn't it more likely that it's CBS corporate policy extending down the chain as time goes by?
