Obviously, traffic is down
Is it though, I've seen lots more first time posters recently, than in my other time here.
re your points
1) It's not just about new traffic, but the current database of useful info and threads. Despite your wishes expressed elsewhere, VE and VF (and especially ZB) are not identical, so having separate areas one click apart keeps people's area of interest all in one place. Having to wade through lots of VE thread for that one bit of VF info would be a pain.
3) Youtube thread is for random $hit. No-one seems to mind a useful/interesting video having its own thread and discussion.
4) Yep, but the profile/showcase does this already, if someone is so inclined. Otherwise popular/active threads stay near the top anyway
6) Yeah no. Enough commodore (or even wider holden) enthusiasts to keep it focussed.
Mostly, I think you underestimate:
- the ability for people to find things. The number of necro thread digs shows the search function works well.
- and their attention spans - you're proposing changes that don't decrease click through requirements (front page -> specific model forum vs front page -> grouped models) for no stated benefit
