A Different Kind of Linkrot

I've increasingly noticed that searching the web for answers to various technical questions gets me a lot of dead-ends or infinite loops. For example, when searching recently for information on libnss-ldap and libnss-compat, I found this forum thread: http://www.linuxforums.org/forum/miscellaneous/172807-name-service-switch-file-nsswitch-conf-what-compat.html. It conveniently doesn't answer the question -- instead referring the reader to search Google. I ended up using different query terms and finding what I was looking for but as I said, this is happening more and more.

I find it interesting and somewhat bothersome that these types of responses -- typically snarky to boot -- are becoming more prevalent in search results and I hope it doesn't get too out of hand.
