I had just moved my blog to a new host. I had done an import of my blog using the Wordpress plugin instead of just exporting the entire database to help clean things up.

I forgot to install the gist plugin so my blog post no longer contained the code. I also had 3 different domains serving the same blog due to a misconfiguration with Nginx which caused my blog to take a temporary hit on Google.

I've since addressed those things so hopefully those will make my post actually appear in a google search.
