It is absurd how much computing power is wasted on dynamically generating what is effectively static content, like blogs.
A simple blog should not require an SQL database and complex software stacks that are executed whenever someone visits the site.
Instead, consider using a static website generator like Pelican, or one of the many alternatives.
Write articles and blog posts in a simple, human-readable markup language such as Markdown or ReStructuredText.
Manage your documents in git. Run the generator to recreate the HTML and update Atom/RSS feeds.
The resulting website is blazing fast and can be hosted on dirt cheap servers.
More simplicity on the Internet please.
