"I don't know how people have the time to create for their shop if they spend so much time on multiple teams."
Well, it depends on what it is you do. I spent a week going through my photograph backlog, editing pictures, etc., so I'm not actually creating anything on a regular basis - I'll just snap a shot if something calls out to me.
I'm in about a dozen teams right now, I think? And looking to reduce to just ten to keep them manageable, but I'm not sure which ones I'd cut. I'd like to join more teams like Etsy Success where people actually talk about things, and I'm definitely not cutting the European Street team or fPOE, but everything else is up in the air. (I'm newish to the forums/teams.)
