This is why I use GitHub pages. Jekyll is good enough, and with GH pages it's super simple. If GitHub were to ever do something weird with it, I can get any static hosting and do the jekyll stuff myself and still control it.

And a static site is much simpler than, say, a Rails-based site (the other thing I was considering when setting it up). Any hosting will do, and I only have to worry about exploits in the web server, not the framework.
