This is exactly the problem I tried to emphasise when I wrote about wiki-erosion. Some solutions would be:
- Move wikiprojects to meta;
- Actively search for specialist users on smaller projects and invite them to join the meta-Wikiprojects;
- The Wikiprojects at meta should make one or two 1000-article lists about their subjects (with links to FA/GA status articles).
The key seems to me more communication and cooperation between different projects. There is of course a huge language barrier, but being European, I think we can overcome this when we carefully read each other's comments.
The bias toward the Anglo-Saxon world due to more translation from wp-en (than, for example, from wp-de, wp-ja or wp-fr) is not just a Russian problem. At wp-nl, the same problem exists.
