I'd love to see an option to post 'blogposts' onto my activity feed, for people to see (and perhaps an option to make a post private, so I can write in my 'diary' on superbetter or choose to share my thoughts). It's nice for quests as Fear vs Anxiety where you post thoughts and share it with your allies. The comment space is kind of small and doesn't invite for long, provocking (positive!) thoughts. We can also use a blogpost to tell about our day at the end of the day, tell in detail about what quest we did, etc.
