This blog is changing its appearance by moving its engine from Serendipity to WordPress. The new engine should make it more convenient to leave comments and to interact with the blog content. Markdown editing is enabled. The old blog will remain available until all links are properly redirected. According to wappalyzer.com, WordPress currently dominates the market of Content Management Systems (CMS). According to builtwith.com, it powers 50% of all websites on the entire Internet. This is another success story for free and open-source software. The WordPress software was originally developed by Matt Mullenweg and Mike Little and is released under the GPL license.
