I can relate.
I joined this board many years after leaving the WT so it probably filled a different kind of need than to most, but a kind of need nonetheless -- revisiting the "world of my youth" as it were. I found it even more interesting than I would have thought and have enjoyed it for almost 6 years now -- with ups and downs of course. But this is waning -- steadily, I feel. The other day I referred to a not so old thread of mine (2 years ago) and while I skimmed through it I realised how much this board has changed since, as so many people left (I'm not discussing cause or effect here). I have changed too no doubt, but what struck me is I was still interested in that old thread, and I feel the same kind or level of interest in current discussions more and more rarely.
Ironically I had left for a few months when JWD was closing and started posting again when JWN came up, thinking the re-opening to new members would revive the interest I found in it. It has to an extent, but not quite like it had been. But then I must be the nostalgic type (that's what brought me here in the first place). :)
