Whoa. 130+ responses in 24 hours.
Why does this matter so much? Lots of people on here use obvious aliases ("Cal Wheeler", "TJim", "Goat Crapp.") I suspect many of those who use more normal sounding names are also using pen names. Who cares?
If I had it to do all over again, I'd certainly use an alias. Some nutcase went to the immense trouble of researching my phone number (which is hard to get) and calls my house from time to time now at 2 in the morning to scream that I'm a moron who knows nothing about Jeeps. I strongly suspect that it is someone from this newsgroup. The cat's out of the bag now, so there's no point in switching to an alias, but I've definitely learned my lesson on using my real name.
