In the 3 years or so that this blog has been up, I've always been uneasy about it. A couple of reasons for this:
Firstly, Wordpress, the underlying platform, consists of a bunch of PHP scripts wrapped around a MySQL database. By far the most frequent security issues I've seen come sites running PHP. Drupal, Joomla, et al. are all easily hackable and WordPress is no exception. I update WordPress religiously on my system and I'm still afraid that someone is going to use some zero-day PHP exploit to hack me.
Less dangerously, but more annoyingly, editing articles for the blog requires that I log into my site local instance of WordPress and use the app to edit the article. This is not terribly hard, but just hard enough that I don't like doing it. Why can't I just fire up vi (startup time = ~300ms) and start writing? Hence in 3 years, I've written maybe 10 articles total. In fact, I've just played with Pelican for a bit and it was incredibly easy to add and edit articles. I'm now writing this post in WordPress and by comparison it is slow as molasses, and inelegant to type this into a web window.
I started looking at static site generators a while back. The first was Blosxom, which came out 12 years ago apparently. I first investigated it in 2004. It had promise back then, but was still rough around the edges.
I have since discovered Pelican, thanks to dotCommie. It's written in Python, uses Markdown/reStructured Text as input, and with the magic of templates (it uses Jinja), generates totally static content. Which is all I need. I've been playing around with it and like what I see so far. I will switch the entire site over when I find some free time.
