I think that its the puff syndrome. "Gilded wings and giant things make way for other toys." Everyone changes, their likes their dislikes. I remember one of the originals when I first got on here left to build AC Cobra kit cars for example. I didn't get it and I like cobras but it made him happy. I guess for some of us to stay static is OK and for others it is just on to bigger 'n' better things.
