It was me. Obviously.
I was trying to change something in the layout of this blog and the whole thing crapped the bed for me. All I was doing was dropping the About Me section that had been so prominently featured at the top right and replacing it with a Google+ badge. And it all went to pot, or maybe just flew to Denver, and now my blog has neither my About Me or my Google+ badge.
I'll keep trying to get it back so visitors know who this blog belongs to but until then, that's an empty lonely corner up there.
