When I first view one article, e.g. http://www.christianalfoni.com/articles/2016_03_27_Creating-apps-with-observables, then bring up the list of articles by clicking the blue header, and then click on another article, e.g. http://www.christianalfoni.com/articles/2015_12_17_Exploring-Elm-part2, the HTML title still is the one belonging to the first article, and so are the comments. Showing wrong comments is the most confusing part of this behaviour.
