I'm not sure if you put out a call for suggestions but since you don't appear to have yelled at anyone for making them can I join in...
Maybe it's just me but I find the comments on the site very scattered between News, Gear and Forums.
So there may be a piece of news which someone sees elsewhere and starts a discussion on the forum, but then it also gets picked up in your News section so people comment there and it ends up with two parallel conversations.
The downside being that if you don't know about the other discussion then it can be days between posts on a subject so it all looks a bit dead, whereas if they were together then it would look more active and I suspect be more active.
And it makes checking the site a bit of a trawl. Discussions about kit could be here or they could be in Gear and you can't always remember, or you miss things that you might have been interested in commenting on.
I don't know how to solve it and I really like being able to comment on the news and gear articles - I think it is a great feature. It's just how to combine it somehow.
