Ironically I think Teak Door is populated by Twunts 
Ouch!
I'm a member of TD, but rarely visit now, not sure why really? I've always enjoyed it and the fact it's 'lightly' moderated and there is some real laugh out loud stuff on there (some of somtamslaps stuff included). And there has always been some great threads of folks travels.
But it's a huge forum and a hang out for TV exiles (which must be worn as a badge of pride), which caters for a completely different market than KF.
For me, KF is mainly a source of information, a place for local expats, or wannabe's like me, to share information and news about the town or other expats. I'm not sure about the cliquey bit though, as I always get the impression most folk on here don't actually know each other, or is that not the case? At the end of the day it's horses for courses and each has it's place and I'm not bothered in the least by these comments.
