I use my own. I spent about 3 weeks making a nice one with rails. It took so long because I was learning rails and also ruby as I went. I use it over managed solutions because I've set it up to easily integrate into any site, it loads insanely fast and has a lot of modern features you would expect (split pane live preview with markdown, auto saving without creating a million drafts, user login to handle authors, etc.). Most managed solutions lack 1 or 2 important features in some way or another and that ruins the experience.
