It seems static pages are becoming more popular what with them being practically unhackable and lighting fast!
As far as my very limited knowledge into this goes Jeckyll seems to be the most popular right now. The setup for this does require a lot more technical chops then a simple PHP/MySQL website though.
If you don’t care about anybody seeing your posts (or don’t mind a hacky solution to lock the entire thing down) you could also use a Etherpad.
I really like the webste and the list @beschizza! Thanks! I will be checking out the single and five file CMS’s too!
