Except TFO was a fictional character; a sock puppet of an MTR regular. I did not know TFO's real identity until he revealed it to me at a road meet. I think it's a fairly open secret these days but I won't otherwise reveal it except to say he's a member of this forum.
All the others mentioned (Tim, Randy, Calrog, etc.) are or were real people.
I heard Calrog was really bad. Why?
Froggie pointed out his many faults rather succinctly upthread. Basically, Carl was very condescending. He would post to MTR every time he uploaded a photo to his site. Not a page of photos. Not a huge dump of photos.
One photo. His idea of a road video was to take a video of himself standing in front of a sign or road talking about it (and then he dropped logs in the punchbowl like the US 31W song.) He incessantly referred to US routes as "federal routes" even though US numbered highways are under the jurisdiction of the states and the numbers are assigned by a voluntary organization, AASHTO, and not by the federal government. He would pay the PRWeb firm to issue press releases when he would go on a trip, or as Froggie mentioned, when he posted an update to his site. He also referred to an "East Coast Hive Mind" because so many of
us the roadgeek community (corrected to not use the inclusive "us" since I'm not located there) are concentrated on the east coast, particularly the mid-Atlantic/eastern seaboard and New England. That led to C.C. Slater designing an "East Coast Hive Mind" logo and selling shirts featuring same on Cafe Press (which several of us bought and started wearing to meets.)
We can all be asses at times, but I'd be hard-pressed to name anyone who actually liked him.
He seems to have dropped off the face of the earth. I don't even know if his Twitter account is still active, since I would never deign to follow it. (He pronounced Twitter as being the future of viatology after Usenet faded into oblivion.)
And about viatology...
