It is much easier (perhaps too easy, considering how
many wikis have zero
active users) to start new languages. However it is surprisingly hard to
find a list of [other] ways to integrate new language/dialect content into
the projects*.
Actually, it's very difficult nowadays. Yes, some of the
recently-created WPs look as if they might be dead for a while, but
most look healthy.
