According to SiteMatrix we have 739 projects at the moment. There are three master partitions for the servers: s1 for enwiki only, s2 for 19 other projects and s3 for all the rest (that's 719 projects).
My homewiki is one of those 719 projects. And I feel a bit neglected. Replication is halted since 34 days. LuceneSearch 2.1 is active on enwiki since October and on dewiki and some other big wikis since December. Most other wikis have still no access to the new features. Even the "+incategory:" feature which is active on enwiki since April 2008 is not active on most wikis as of February 2009.
It seems, we are very low at the priority list.
