Ha!
I think it's probably a bit of a mix of all of those reasons. not sure how many "original" member are still on here from when I first joined, but the Internet (and especially Social media) has advanced quite a bit since then, and sometimes it becomes a case of too much choice.
Also, I have no idea how many NSX are left, they do seem to get fewer.
Speaking for myself, I haven't used the forum much as I haven't been using my car that much, however, I am slowly getting back into it (it's currently getting a bit of work done) and then hopefully will be more active on here again.
Hope that helps,
cheers
