Recently, John convinced me not to respond to anonymous comments. That's a good rule, seems to me.
However, it is possible for a commenter to display a name, but stay pretty much anonymous by not allowing your profile to be viewed publicly. That happened in yesterday's string of comments.
So, what do you think? Should bloggers respond to anonymous or name-only comments? Or should bloggers limit the back-and-forth commenting to either people we know or who have a blog of their own?
