An alternative way for our community may be not to wait for another "define-commit-private beta iteration", but to use increase the visibility of Open Science agenda at Academia Stack Exchange site.
Academia Stack Exchange is already a popular site, and questions on Open Science would be definitely on-topic there. Here there is a selection of some relevant tags from that site:
- open science - 27 questions
- reproducible research - 24 questions
- software - 107 questions
- open access - 64 questions
- code - 39 questions
Following these links, you may find examples of questions which would be perfectly on-topic at OpenScience Q&A site.
I'd expect that the audience of Academia and of the proposed OpenScience site would have a large intersection. So maybe we could use this situation to re-think whether to go with a new proposal (and wait another several months?), or to increase the visibility of Open Science agenda and the quality of questions and answers on this subject on Academia.SE (this activity could be started immediately)?
Proposal: Open Science
P.S. See also Open Science is a duplicate (subset) of academia.SE
