Update to this: I got my invite and started setting it up. Pretty impressed so far, I really like their TOU and the things listed (no resellers, MUST be handmade, etc.) make me think their goal is to be what Etsy used to be (and is not now). My biggest hurdle on Etsy now are the stupid download people - looks like this site won’t have that, which is a plus for me.
The policies state they’re going to follow marketplace facilitator rules and collect taxes, so they’re not just looking to be a front like some of the other Etsy imitators.
I have no interest in classes, but can see that bringing customers to the site.
And lastly, Michael’s is one of the only craft/hobby places that have actually survived, so maybe they know what they’re doing?
It might be a flop, but I’m willing to put in a minimum of effort to see what happens.
