I spent some time this evening chatting with Thomas Waldmann on #moin at irc.freenode.net. MoinMoin is currently at 1.0, though 1.1 is just around the corner. Hopefully 1.1 will include some caching support which should speed things up (Slashotting a MoinMoin wiki is not recommended) a bit. 1.1 should also bring compatability with persistance, such as the Twisted Framework and mod_python. More details on that can be found at the mailing list archives. Planned features for 1.2 include some darn smart internationalization. Linking WikiNames across languages sounds like a headache, but there is a working demo up and running.
Aparently Thomas isn’t much of a Python guy, but he loves MoinMoin and is pleased to be working in Python.
