While doing a quick search on this site, I happened across a post from 2007 talking about Viral Tags. Doing so reminded me that I should probably go through the 1,500+ posts on here to remove some of the stupid things I did many years ago in a bid to gain Google PR juice1. A quick check shows that 95% of the links in this post are dead and gone. The ones that do load are for static landing pages suggesting I buy the domain and do something with it.
I'm actually sort of glad this silly stuff has stopped.
