I could have done this without asking on Meta, but I think that this is a good way for spreading and maintaining information across both sites and more aspects of a topic may could be enlightened given the majority, the experience and the expertise of those who are involved.
I would say yes, with the caveats:
- The question doesn't already exist, in some form, on DA.
- You're not blantly just copy/pasting over content in bulk.
- It's summarizing a long winded thread/page to a more concise question/answer format.
- It's a topic considered on topic here.
In short, novel questions brought up / solved on d.o. are ok to post if they're on topic here and been trimmed down to fit the Q&A format.
