Steve, I'd encourage you to stick around. I agree, it has been rather dead lately. I began following this forum some time ago, but I think it was after Carleen Zink had passed away. I wish I could have been here for her tenure - it certainly seemed like it was a lively place. That being said, I've been in many great discussions on here.
I've noticed that the website Columbophile has been very popular, involving quite a bit of banter as the author makes regular posts. Perhaps a change in format here would help? The shows are just as old on his website as they are on here, but something resonates.
True, I also like columbophile, he makes long and interesting reviews of the episodes, but even so I'll continue following both, more chance to find interesting topics; like you unfortunately I wasn't on this forum yet when cassavetes was around and I agree it was much more active.
