@SteveIves (1) No SE site allows completely open ended or opinion based questions - closing such questions on Area 51 is completely normal. (2) Area 51 is open to all, as the whole point of the proposal system to put it before as many eyes as possible in order to give each site the best chance it can have to succeed. (3) You would do well to stop assuming things about me. What could possibly have ever made you think I have no interest in the site?

@steve It doesn't take any domain experience to recognise shopping list questions and super opinion based questions. The questions I didn't understand I left alone. And see the answers below for other people that also identified many shopping list questions etc.

Putting the question of whether it should be a separate site to the side, that proposal definitely needs lots more eyes on it. I just used up all of today's close votes and almost all my downvotes on it. (Not implying all my votes are right, I'm not very familiar with the topic, just looking for things which don't seem to fit the SE format.) There's a huge number of broad/opinion questions.
