I'd also note that since we're just beginning a period of migration, plus a period of mass-transfer of large amounts of content, what happens in the next couple of months is not useful data at all. I don't plan to make any major decisions on forum arrangement during atypical periods. After Oct 29th might be a better time to start looking at trends.
Eh, if that is the case then essentially I'm going to get limited use out of ENWorld until the end of next month.

It's probably my lurker roots shining through, but my typical daily visit to ENWorld is a two-step process - A, I visit the news page to see if there are any interesting articles or announcements, followed by B, visiting the 5E general forum and browse through the new posts made to threads I've been following or to see if there are new threads I'm interested in following.
Since the merging experiment began I've found myself basically skipping B. I gave it a go for the first several days, but for me the "identify a promising new thread" process was typically low-effort - I'd skim ~20 thread titles and see if any sounded interesting. Since a significant portion of those are now topics I personally find uninteresting, I'm no longer able to do that and have essentially abandoned the 5E general board now. I'm not currently following any of the threads there and without a "feed" of new topics to replace them I'm only visiting the front news page these days. Interesting comments on a news article might occasionally bring me over but that's about it.
I'm not saying it's got to be my way or the highway and I'm sympathetic to the reality that segregating those threads in their own ghetto starves them of views and posts, but I don't see an easy compromise as without the ability to filter out content folks aren't interested in, you'rr essentially reducing the available amount of content folks ARE interested in. Sure, the threads are still there, and I could find them if I was willing to spend 2-3x the amount of time looking for them, but... I'm not. And I think that effect will have repercussions on the quality of the discussion down the road as well. If enough folks are put off by having to dig through content to find something they're interested in, those posters won't end up contributing to said threads and the quality of the conversation decreases over time.
A good analogy might be a party with lots of "areas" - you've got folks talking sports by the bar, folks talking politics over by the snack table, folks discussing Game of Thrones and playing pool by the pool table and folks talking about their favorite movies on the patio. If you remove all those landmarks and mix everyone up in one big room, I've got to navigate past a lot of other conversations about other stuff in order to find someone else who wants to talk about Game of Thrones. The same folks are there but I've got to put in more work to avoid conversations about politics (ugh) or sports (Why yes, I do think the Green Bay Patriots will win the penant this year). I wouldn't ask the host of the party to censor the other party goers in favor of my GoT convo, but if I'm having trouble finding a group talking about something interesting at the party I'm probably just going to go home early.
Just my two cents.
