Proposal: Open Science
I'm going to go further than the related question Should open science questions just be asked on academia.SE?
I can't see any reason why this isn't a subset of Academia.SE, and would draw questions and traffic away from that already-launched site.
The only questions from the definition phase that couldn't be asked on Academia.SE are the many shopping questions (and maybe some are boat-programming questions too). And I rather suspect you wouldn't want those anyway, once it came down to it.
So I propose closing the proposal: if there are any good questions that you feel that would in reality be asked on a beta Open Science that couldn't be asked on Academia.SE, plesae do come over to meta.Academia to discuss whether Academia.SE's scope should be expanded to include them, or not.
