The strongest promotion -- and actually your proposal goes into this
direction -- would be to rebrand the sister projects,
and then integrate
them tighter. A first step, and a necessity before any further integration
could happen, would be to give up the many different brands the Wikimedia
movement has, and huddle together under one flag.
As said, your proposal suggests that - it doesn't say "Wikiquote", it just
says "Quotes", etc. This basically means that it is not Wikiquote anymore,
but Wikipedia Quotes.
This is a very old issue, in which I don't have strong feelings.
it is a real
paradigm shift, and I would (personally) agree on that, even
if I'm very jelous of the Wikisource brand, for example. People just don't
get it, they always think about Wikipedia, all the time,
and it's a long time I've given up explaining them I don't work in
Without that, I am afraid, such a strong integration
between the projects
always remains fragile and touchy, because the projects - if they are not
mere supporting projects like Commons or Wikidata anyway - might feel
offended and debranded every time they are integrated in such a way.
I'm not really sure about that.
But I have no data, just opinions.
Anyway, here the discussion is going on steadily, and there are other
options ready that go in the direction
we were suggesting before.
(look Option 5)
