This Discuss installation has now passed 100,000 threads. That's going to be nearly half a million comments or perhaps even more, assuming few threads with no replies at all.
I still remember the old forum site, my username got chewed up when that changed, so I guess this installation was implemented in perhaps 2011-2012. That one felt very random, this one has always been well-organized, even over organized.
Its been a good run, and seems ready to go another several years at least. I did notice some little link styling problem popped up some time ago, where one ring of color around the content was mis-placed, I wonder who fixed it
The biggest problem is its not really working on mobile. That's a real drawback tbh.
