Too many cliques?

Not so far as I can see. We all have something to share with others in QJ, and we all have something to learn from others. I have never sensed any barriers to this kind of exchange on QJ due to cliques. Yes, some people are interested in some topics and not in others, and sometimes the same people are interested in many of the same topics. But that's to be expected, and it doesn't mean those subgroups are cliques. In any case, the defining feature of all cliques is exclusion, and in QJ the excluders (if there are any) would seem to be hurt far more than the excludees.

Too much Q and not enough BW?

Well it's certainly true that the majority of active QJers seem to spend more time canoe tripping in Quetico than in BWCA. I think it's natural to expect that their trip reports, camping and fishing tips, shared experiences, and questions to the group deal more with Q than B-dub.

But posting takes time and effort: sites like QJ only work if a significant number of people donate their time in this way on a regular basis. If most QJers make their donations in the form of Quetico-focused posts, I'm grateful for what I get. bwca.com has been around for over ten years, and it's natural that many of the people willing and able to donate their time and BW expertise should gravitate there. I don't see any unfriendliness towards BWCA paddlers anywhere on QJ - rather the doors seem to me to be wide open to people willing to post on non-Quetico-related topics.

FWIW, just scanning the headers and menus on my current page, I count five references / links to Quetico and five to Boundary Waters. I'm finding it hard to see a problem here.
