I like that you can edit pages easily using WYSIWIG editor or by hand coding if needed! You also have some options to install plugins for extra features such as calendars etc., which are not available out off box (yet).
It's free software so there isn't much more than what comes standard but this works well enough without any major issues/bugs reported yet either. We use it primarily internally at our school website - we don’t really utilize all its potential though mainly just publishing…
