Hah I was recently looking at that subreddit and yeah that’s why I don’t like the idea of that kind of group buy. It’s a gamble on everything working out and everyone doing the right things. I also would argue that requesting a known designer/manufacturer to make N of a specific item is different than asking an unknown designer to do so for the first time. Terminology aside, this is my original point: that is a risky way of doing things and communicates to the consumer that the product is unlikely to just get made and be available.
Absolutely. If one was uncharitable, one might suggest the reason that some of those group-buy-powered companies run their own storefront instead of Kickstarter is so that their customers associate them with "buying" and not with "funding".
