Okay, I've managed to move most of the important articles over and spent some time getting things working.

Here's what Bitakora has:

1. Great multiuser support
2. Clean and simple admin interface

Here's what it needs:

1. Split articles (read more...)
2. Spam prevention
3. More configuration options (I had to hack dhtml and py files to cut the number of articles per page down to 5 from 10).
4. RSS feeds by tag
