I have also used markdown files in git for quite some time. When I was running Windows 7, I added my notes folder to the Document library and was able to search my notes from the start menu - that was really great. But then Windows search got broken in Windows 8+ and I started looking for alternatives. I played with OneNote for a while, but missed VIM key bindings, markdown and easy online access to my notes (OneNote online editor is quite heavy). About two months ago I switched to a private Wordpress and till now I am really happy: full-text search works like a charm, I can tag my notes, use markdown (even with Latex expressions) and for cheat sheets (or field notes) I use pages.
