It's about a small number of panel shows that never had mass audiences to begin with. Adding Maria's show a few years ago was ground-breaking.
And it's on a website with a lower activity level all the time. When this thread was getting 1,000 responses, you could see many new threads every hour all day long. Now I can check the forum at 10PM daily and see maybe 10 new threads since the last time I looked at 6 PM. And the number of new things showing up overnight gets smaller every time I think about it.
So it's not just each regular here that is aging.
Maybe so but you are ignoring what RN does. She has 5000-6000 post threads all the time. Basically, she is FR these days.
