As a former copy editor (a strictly amateur school type thing) I realize that by naming this thing mgoblog I've created a severe annoyance by creating a proper noun that's all lowercase and therefore confusing as hell. People are going to capitalize this, as is their right. However, if you care to get it "right," the way to do it is this: MGoBlog or Mgoblog. Whichever. I occasionally see "MGOblog" like MGO is an acronym of some sort. It isn't. It's "M Go Blog." "M Go Blue" is a common thing to see on signs, license plates, or official athletics sites around Michigan. It's a play on words.
Yes, this is totally, unbelievably anal. I abase myself.
