Some questions here could potentially be on-topic for multiple Stack Exchange sites. That's okay, there's no reason we can't duplicate as long as the questions have a different slant on different sites.
For example:
This recent question on reference documentation, for example, would work well on Stack Overflow, but would get substantially different answers, since that's a community of programmers, not writers.
Thesis questions could work equally well on Academia.
ESL questions like this one would probably be welcomed at English Language Learners
Grammar questions are discouraged here unless they relate to writing directly, but some questions straddle the line between Writers and the English Language and Usage site.
My question is: How can we reach out to other sites, making them aware that Writers exists as a resource? I don't want to be overly pushy or spammy, or try to get lots of questions migrated here (particularly at the expense of other small beta sites) but we can probably help out with any writing-oriented problems that are posted elsewhere.
Is this even a good idea? Maybe we should we focus on publicizing the site outside of the network?
