> Seeing the activity flow made this click for me. I like that someone can just say “I’m cycling next week,” let people join, and figure out the time afterwards instead of creating a fully formed event upfront.

Thank you! Nice to hear this makes sense to someone other than myself :)

> Curious which has been the better wedge so far: bringing existing groups and their members over, or creating new local connections through individual activity posts?

I'll have to get back to you on that hah! I've only launched the activities this week, so we shall see!
