What I personally miss most compared to the old site, are the threads on movies (especially those, I miss the short movies), books, podcasts, comics, food, travel experiences, etc.
Owen didn't initiate those threads, but the community and they kept feeding them with good stuff. I would hope that the same people who did this in the old site would find it in themselves to reestablish those threads. Personally they were a major source of input for my "cultural time". Maybe the site's editors can choose a "topic of the month" sort of thing, where we all discuss movies for instance, to get the threads going and keep us focused for the start?
