I agree with Psychotic. It seems like the whole, "omg I registered 3 years before you... remember Ezboard?" thing was more common awhile back. I don't see too much of it these days.

But I think it's all perspective. A person who joined last year and a person who joined 5 years ago are going to see the forums differently.

The "golden age" will generally be the first year that a person joins. That's usually how things work. So the "golden age" isn't a fixed thing, it's different for everyone.
