The site is almost presentable at this point; I have started to bring over some blog entries/articles that were originally published elsewhere. Most of these were originally published in my personal blog, so they should be considered cross-posts. Articles that form a series can be grouped using tags.
One might wonder whether “articles”, especially the ones that weren’t originally blog entries should be in a separate collection, or even multiple collections. Jekyll, however, doesn’t make it easy to put a single page in two places, and it would confuse search engines. It does make it easy to create a “landing page” for each tag of interest.
