I've been using Zim [1] as a knowledge database for around 2 years. I don't like depending on online solutions which may suddenly disappear.

Together with some plugins for managing tasks, git and some script for synchronizing repositories, it has been working great.

There are some limitations on this approach (ie, two persons editing the same page concurrently is a no-no), but for my use-case it works perfectly.

I find it much more intuitive than org-mode, and the fact that it auto-generates a "global" task list based on items spread across the whole notebook makes it much easier to prioritize things.

I like Zim. For my Batcave I switched from Tiddlywiki to Tomboy to Zim to Notecase Pro and finally switched from that over to files and folders using the Geany editor and a sync service. So far this is the combination that seems to survive software, OS, and environment changes best. Even on Android it's not perfect, but it makes me happier than e.g. trying to use Zim on Android :-)
