This is excellent practical advice. The invite-only approach especially resonates - we're actually planning something similar.

I'm curious about the cold start dilemma though: invite-only is great for quality, but creates a chicken-and-egg problem for early adoption. Do you think it's worth the slower growth from day one?

Also, for initial promotion - better to avoid platforms like Twitter (where average user quality is lower) and focus on higher-quality channels, even if reach is smaller?

Would love your thoughts on balancing growth vs quality in early stages.
