Don't like the new format.
I like having a home page that lists the most recent threads on a rolling page so I can see what the current and popular conversations are. Anything older or specific I can look for.
The new post page only shows the most recent posts since my last visit, which today was two threads and that page doesn't bookmark either.
Here's an exmple of a forum that I like the look of:

Currently it's too much work to find current and popular topics.
