This sure seems to me like a good counterargument against all those who insist that people use their “real names” when posting comments. Maybe we’d all be better off if everyone made up some sort of unique “handle” (e.g., millard1258, as used at http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=330075405123) to identify themselves instead of using first and last names–especially if they have common names like Sue Smith (or, in my case, Tom). But even those “handles” could be used to impersonate someone–so the problem remains if it’s intentional. Plus, I’m not creative enough for that, so I’ll stick with Tom for now, even though there is at least one other person out there who posts on sg blogs and boards under the simple name Tom.
