I've definitely been spending more and more time on ATP, but there are still some places I check into on DG... most of those threads are still "visible" to me whether or not I subscribe, but I decided to renew this morning in order to be able to post in those forums. It's not the great investment it used to be, LOL. I agree, as subscribership diminishes (and as remaining subscribers become more frustrated and less active), the site founders.
Meanwhile, ATP is definitely taking on a larger and more visible role with the acquisition of NGA! There's been so much done here already in a relatively short time... I'm really excited about seeing where the next 5 or 10 years takes us!
