I don't think the forum has died, but I always felt this place was not versatile enough. It was set up for politics, it was set up by someone who was trying to attract that one ring circus. By sheer chance, it was in the right place at the right time and back then, it had a thread view, and justoffal said "Let's head over to Political Jack" and we all followed. The self moderation in place is way better than any editor at Slate could hope to achieve. We forget how bad the treatment was from Slate and how ridiculously the rules were abused.
If I had to point at failures - and these were probably unavoidable - I would say there was 2 big failures that cost this forum most of the circulation it lost. First, Dave didn't adjust to the clientelle; he stuck with his format, which was good for politics, but he lost the arts and humanities and special interests ... he crushed them all into politics; even economics was narrowed to government focus. He lost half the Fray right there. Then, over time, thread view was phased out... I left the place when that happened, was gone for over a year. He probably didn't lose many others over that single item, but it limited the conversation, and so it was a subtle influence, but the place lost some of its luster, threadview was the whole purpose for posting at Slate Fray, the whole community was built around it, so when PJ lost threadview, it was like losing the Fray all over again. When Fraysters do pop in from time to time, it hurts that they don't have that familiar architecture. Threads is how we learned to post, maybe we have grown up past that, but it still attracts us, and just like grown-ups acting like kids when they are having fun, it's a nice feature to have in the forum.
Time was, I put up a post in Money box, in 5 minutes time, I had 600 views. Same would happen over in BestoftheFray. Here, we use "Recent Posts" as if it was a Fray for the entire forum (which, I guess it is) - and the feature of moving recent posts to the top; that combines all the old tools into one; it is so effective, I'm afraid if we still had threadview, there would be nothing but fights happening. human nature is a real bitch.
All in all, I've enjoyed posting here more since I came back (I returned to put up that apology on the two aspects of the holy spirit) Spring 2015... I would say I've enjoyed posting here more than any other place I posted, not at first, but in the last 2 years; I like the pace, I like the way BD's blog has worked out, it is easy on my old nerves, I'm not into flame wars any more.
I don't think the forum is dying, I think it has slowed, but when guys like Pogue Mahone drop by, you know people know about the place, you've got some tough veteran posters here and you get visited by the same, it is a tough place for a young poster to fit into... not much you can do about that, you can't teach these old dogs new tricks, if you can keep the inmates from rioting, you gotta be happy with that. New posters are what grows a forum; we have no feed from a mainstream media, so growth has to happen organically, and really, a bunch of political hacks are not going to go for Christian nurturing; it just isn't their style. So, don't expect any exponental growth any time soon, at the same time, the place has a good mix of writers that are talented; maybe we are not the cream of the old fray, but we have stayed with it, the quality is pretty good around here, everyone knows how to play the game, that's not easy to come by, it offers a sandbox for people to come play in; it worked for me, I came back to play in the sandbox and I'm still getting my hands dirty. When the community still has some vibrancy, that's a sign of life, so if it is living, it ain't dying; not yet, anyway.
