When there's a picture of you in your Wikipedia article from a public event you chose to speak at, you've made yourself just a "Hey, I know that guy!" away from being outed. At that point, I don't think you can claim it's a major affront when someone puts public information together to identify you.
I think the "who is why the lucky stiff" blog is odd and a bit dickish, but I'm not appalled.
I'm also skeptical of that purported outing as the cause of all this; this is one story I think that a bunch of people chatting and commenting are precisely the least well-suited way to work out the truth.
It's possible to be truly unidentified and uncelebrated. It's not possible to do so while maintaining a specific identity, especially after it becomes well-known. That he maintained this identity well after it gained celebrity wasn't exactly forced on him.
