for me it's the ability to publish my blog to a static set of html files (and have pretty-printed source code). The other thing I love is the agenda: having a set of files spread apart (I keep 3: personal, work, random) and add todos in there as part of free text, and be able to keep track of them in a centralized place is priceless. I also use those files as a journal, tagging them and searching later is very easy and a great way to document things (for personal purposes).
