Huge spikes of viewers and just started

This is maybe my 3rd real stream and I ended up getting an active 8-10 people with 4-6 chatting. They were great and it was very enjoyable. Anyone have tips on trying to keep in-touch? I don't wanna ask for follows but I genuinely enjoyed playing with them and hosting a platform we could all play together on.

I think I'm too small for a discord and maybe if I'm active they'll return (I hope)
