It's the Twitter-like nature of the new forum that I like the most. Just sharing garbage thoughts that don't fit into a forum thread (either new or existing) and ending up with those 'off the cuff' conversations is a thing I really enjoy.
Yup. Plus having the notifications means I can just keep Doomworld open in a tab, and my posts don't feel as much 'set and forget' as they used to. Much easier for me to keep a forum conversation going now.
