I want to start by saying that it gives me immense pleasure (yes, I said pleasure) as somebody with zero current teams to post in this very thread because MikeT, the man with only one team but a million terrible opinions, thought that only active coaches should be able to participate in these forums.
That being said, he was a plague upon this house. Of all the users that could be said to have truly been a detriment to the HD community, its my opinion that he stood alone. Hell, other prolific users at least left something worthwhile in their wake -- kernels eventually came around and then managed to actually ingratiated himself into the hearts of most coaches...etta not only managed to bring the entire HD community together in a way that will probably never happen again but also managed to produce the largest outpouring of collective user knowledge in the process...and Only (who I know will see this, mad love, but its true) at least taught us a collective life lesson about unbridled passion and pure destruction.
But Mike - through sheer unrelenting repetition, unwillingness to engage in any substantive argument, disingenuousness, unearned sense of authority, and pure uncut smarminess - managed to systemically degrade conversation across the boards in a way that I don't think a lot of people realize. I couldn't imagine making thousands upon thousands upon thousands of posts somewhere then having the vast majority of users who I personally interacted with label me as some shade of 'toxic'.
And that's the thing about toxicity...events like Chernobyl are largely the exception...its the small consistent exposures over long periods of time that bring the party to a halt long before people are ready to go home.
