My experience of TK, and I'm not alone in this, has been a mixture of dreary passive-aggressive behaviour and insensitive/aggressive behaviour (e.g. the Memes thread, where his/her pattern was constant criticism of what other people posted and very little contribution of their own). The name changing went from very occasional to almost constant only after a whole serious of people called him/her out for shit behaviour, after which the pattern changed but didn't improve. TK quite possibly entered more block lists than any other forumenger ever, in a very short time.
The tedious repetition on this thread of a "joke" that clearly irritates many more people than it amuses is hardly evidence of value. The grim resolution to repeat it when this has been spelt out is entirely characteristic. It makes Scoble look empathic in comparison. "Here's a thread where most contributors feel much more strongly about the topic than usual. How can I contribute? I know, I'll be a fucking irritant."
Of course not, it's T*** K***. It's marginally less pathetic than the constantly changing username.
