EnWS members could teach us a lot, with their big community,
with their technological advancement, and also with the simple fact that for them is much *easier* to write
messages in English :D
The same, but different, can be said about de.WS and fr.WS. These are big communities and big projects and we could learn so much.
We need people.
We need more involvement, and the rest will follow.
I deeply believe that we have, right now, all the competences, the experience, the technological expertise to make Wikisource scale globally.
But we can do that only if we are together, and the best of us teach the rest when they can.
This is important because complex problem (like, Structured Metadata, or Wikidata integration)
*need* to have different minds and competences to be coped with.
Few scattered people won't solve them.
We probably need to feel more like a community. I think we are, or at least I think that we can be it :-)
These are broad principles.
I can think of more concrete and specific things too, but I wanted to give you my main insight as well :-)
