I wouldn’t only go by the “new” thread count - press G - followed by L to see all the latest posts - there is much activity in existing threads.
The conversations, discussions, sharing, etc. continues in existing threads.
A lot of topics already covered by existing threads, pick up from there; dive into the conversation - no need to always start a new one. I see a lot of activity - updates every few minutes.
As soon as a major update comes, the forum will likely show hundreds of new threads again and the mods will be busy sorting them - some of them into many existing threads.
