When I'm reading a comment written by a name that I've seen enough to associate a personality with, I'm almost always aware of whose comment it is. But, when it's not a name I know well, I'm not consciously aware of having looked at the name and made that determination.
So I think I must always read the name, and if my brain doesn't recognize it, it automatically filters it out.
This is a thread where people can ask questions that they would ordinarily feel embarrassed for not knowing the answer to. The previous "stupid" questions thread went to over 800 comments in two and a half weeks, so I think it's time for a new one.
