>>transitioned entirely to Facebook
I'm seeing TONS of this, too.
Zuck has copied all the successful social site features. I don't understand why he doesn't have teams copy Shopify's ecommerce features, Open Table's reservation system, Viator's booking features... and promptly dominate small-medium biz. Think of all the advantages FB would have by combining retail/reservations/bookings with the giant social and advertising platform. Half the feed could include "buy now" and "book now" buttons.
Also, if FB marketplace weren't such an afterthought, it could be an ebay killer.
Anyway back the title topic.. Austin has food delivery robots downtown. So far, they still have human babysitters.
