I, too, agree that it falls down to the member base. Forgive me if I sound too pessimistic in my opinion that there aren't many straightforward things we could change about the Round Table.
It is my opinion that the number one factor responsible for D&D's previous success, as well as the lack of activity currently seen at the Round Table is regulars, as pointed out by Stormbringer. The old D&D had its success due to a balance of regulars - those who argued with more passion vs. those who had moderation, as well as those who, in broad brush strokes, sat on the left vs. the right. There were "rivalries" that bled into contentious discussions across many threads, and this has the effect of bringing people in, affecting upon them an emotional response - just in general giving them something easy to respond to.
Also, contention seems to (at least for this community) be a necessary condition to activity. I have a feeling that there's roughly the same number of posters as there always has been, but the back-and-forth between a few posters responsible for much of the activity (let's describe activity as post-per-time) just isn't there. A dispassionate pursuit of knowledge might be noble, but it's heightened emotions gets the fingers typing.
Now to address God's point: did members
want a more relaxed D&D? I'm sitting here and I'm thinking that our (at least my own) perception that members wanted a more relaxed D&D was not entirely accurate. The memberbase at large might have an opinion on D&D, but it might be the case that the although memberbase at large expresses an interest in a more relaxed D&D, it isn't any more motivated to participate in what is now the Round Table. Basically, we based a decision upon the perception of people who aren't into the discussion style of the Round Table, no matter how heated or not it is - people who aren't significant stakeholders in the section.
At the end of the day, I don't believe the Round Table is a place where you just simply talk about things, because I'm sure that's not what captivated regulars in the past. The Round Table is a place where you give arguments, premises and conclusions, and contentious ones at that. I think that aspect is non-negotiable and it means that OCD/D&D/Round Table would have a relatively narrow following, compared to more relaxed sections. That's just something we have to live with (but keep in mind that it's something that we've always lived with, even if we didn't recognize it).
Now, if we treat the scrutiny and analysis of posts and opinions within the Round Table as a given, then I think it would be appropriate to bring back the contention and controversy. Nobody enjoys a heated conversation for its own sake, but I'll wager that those who are attracted by the analytical style and social-scientific-political subject matter of the Round Table, even if they post there once a month, would rather a section that's more sizzling than flat - even if we would all vent about how polarized the section is from time to time.
In summary, I'm becoming attracted to the idea that it was D&D's contentiousness that made it compelling and that's something the Round Table is missing at the moment. I think the only real solution is to have a moderator or two who will trudge through the little or long while. OCD/D&D came about organically, and while I'm not opposed to having events on principle, I do believe that they need a more established community to be self-sustaining. I think the best solution is to have some person(s) give the section some direction, nudge it along so to speak. I think I have more to say but it's like 4:20 in the morning (blaze it!) so I'll leave it right here and get the fuck to sleep. The fucking birds have started chirping and I will not have my silence :(
At the very least, one thing we can work on for sure is making the distinction between the Treehouse and the Round Table much more clear, since the lack of distinction between the two is hurting both sections right now and everyone seems to agree on that. The question is what exactly shall the distinction be?
Yunno, I've never really liked the idea of "legislating" a distinction between the sections and agree with flight. I feel that a "you'll know it when you see it" approach is best and that was how things were done in the past. The general consensus is that the Round Table is less active than the D&D and OCD days, but interestingly enough, I feel that D&D/OCD was less distinct from GC/OVP back then. I think GC/OVP was doing pretty well back then too. I have a feeling that creating distinctions is going to be less effective than we think it would be. I don't know, it's worth talking about.
Also, also, also. I did a quick count of the post counts of threads created in the two most recent monthly periods (from today back to May 18, and from May 17 up to April 18) and the counts are 343 and 372, respectively. I remember I made a thread about D&D in the mod section wayy back when and I had uploaded some Excel files detailing post counts sums of threads created within a certain month. I can't find the original file on any of my computers and I can't remember where I had uploaded the files, so if somebody could get a hold on those Excel files, that would be highly appreciated. It'd be nice to have some kind of objective measure of activity between now and the past, just for the sake of comparison. From what I remember, 343 and 372 seem to be on the low end of those months that I have recorded but not unprecedentedly low. But that doesn't mean anything unless I have something to compare to. The thread containing these files was probably created between December 2013 and February 2014. I'd be so grateful if I could get my hands on them again :)
