I don't think future ranking adjustments are a bad idea. I imagine that every 10 year old Legendary on this forum could be given a new rank in the future "Legendary II or something" especially if they have achieved a certain number of activity and merit.
Merit
and activity is the key, because there are people who registered years ago who've barely made any contribution to the forum, and there are members with tons of merits who haven't shown a dedication to being here that members with a lot of activity points have.
I think adding a rank that recognizes both, something along the lines of what LoyceV suggested, would be great:
Since this was years ago, by now maybe we need a few more ranks: 2000 Merit/Activity, 4000 and 8000. That's going to take a while.
And yeah, if ranks were added for those levels of activity/merit, it'd take most people a long time to reach them. But wouldn't it be nice if there were actually ranks like that to aspire to?
And congrats to everyone who's at or anywhere near the 10k club. I'm limping along, but I'm sure if I don't die first I'll get there eventually.
