Fewer threads per page = Less Content
The real problem I see with the new forum is with the new graphics and more white space, there definitely appear to be fewer threads on the first page.
Given that people often don't scroll past the first page, that equals fewer active topics, which anectdotally appears to be decreasing participation.
Bike forums certainly doesn't need less meaningful content.
