I'm not going to give you all my reasoning for coming to this conclusion. I'm now going with the first theory and I know the identity of said angry potato. In fairness, I don't think he's particulary trying to hide it either; he left too big a major clue.
Here it is.
My alma mater Villanova is in the Final Four! Take that protestant bitches.I know which local blogger is a Villanova graduate. You can look it up by Googling. I was going to link but since it involves an employer, I won't do that or provide his last name.
I had his name up, and it is a he. But I've decided to take it down. This is why I don't deserve to have more than the 5 readers I normally get when Ben or Lowell don't link to me.
I am fairly convinced I'm right. And I believe it is cowardly to ridicule people anonymously. But I have a visceral dislike for unmasking people and possibly harming them too. So, I did the cowardly, but I think correct thing. I know the identity but I'm not going to reveal it. One reason is because the link that does so also lists the person's employer and somebody's livelihood is not something I want to harm or threaten in any way.
Meanwhile, I have the personal satisfaction that I've solved a mystery. I've always been a fan of mystery novels.
