I think that with the gazillion people on the site now, the good old days are gone. *Today* will be the good old days in 10 years or so. :))
Edit: Also, I think that social media is providing a place where folks are meeting their friends, and it's a natural thing that JWN may be more of a starting point for folks to meet. Then they move on to Facebook, or G+, email, whatever.
Many folks were around long before me, but it sure has exploded with membership since the late 00s.
