So you've probably noticed that I've been wrestling with the blog today. The good news is that I've resolved the loading issues and improved the blog's speed from "D" letter grades at GTMetrix.com to "A/B" grades.
The Disqus comment system vanished for a while due to the settings on the content distribution network (Cloudflare) that I've enabled. The comments are back, but the bad news is that they'll take a few extra seconds to load because I've pushed all Javascript scripts to load after the rest of the page appears. You'll have to wait a few seconds for Disqus, but the site should be noticeably faster in the meantime.
Phew. Frustrating stuff, but a solid outcome.
