Sometimes when I invite an unsuspecting shop to a team I lead, just based on the fact that I love their items and they look like good etsians, they message back to say they're unfamiliar with teams in general and aren't really sure what they're for. Of course it's different from team to team, and Etsy has good articles on the "why would you start a team..." sorts of questions, but I kind of want to hear from all of you, I might just compile a blog post about it.
If you ran into a friend on the street who said she was an etsy fanatic, maybe even a seller, but she gave you a blank look when you mentioned teams and asked what those were all about, what would you tell her? What are your favorite reasons to join teams? What have you gotten out of them? What do you look for in a team to join?
