It was kind of like this in the V-Strom forums that I used to frequent before I traded up to the C14. Two boards, different purposes.
Stromtroopers was like this one, very much a Saturday get together for a little bench racing and good natured "discussion" among friends. Plenty of good tech info, but still fun. V-Strom Riders International is very tech related and can be likened to sitting at Moms house on Sunday morning before church, a little more reverend and moderated.
There was/is no competition between the two, but like ours, each has it's own intended purpose.
As to ZGGTR and COG; I will be active on both. Here the atmosphere is more relaxed and, dare I say, fun. There, maybe a little more "stiff'", but, with it's main purpose, being the front end for COG itself.
