One of several test balloons he ignites over the years, WHWS is a commercial success accumulating more than one million visitors in its first three months alone, an accomplishment given the site’s nature. Very international, WHWS continues to attract a wide audience.|
|May 2007||October 2015||Jens becomes an Invited Expert in W3C’s HTML Working Group. He contributes to HTML there similar to how he contributes to HTML on the WHATWG side or for CSS then again at the W3C: by reviewing, commenting, and translating here and there.|

|April 2008||Jens, with his preference for tailored technical solutions, pushes HTML code optimization by publicly attacking the otherwise undisputed “no omission of tags” boundary (and becoming notorious for it).

|May 2016||Rather late as he soon learns, Jens discovers Round Table. The story quite condensed, he’s a founding member (2016), vice-president (2017/2018), and president (2018/2019) of Round Table 233 Alster-Milchstraße Hamburg.|
|September 2016||If there’s a particular thing to aim for when developing and maintaining websites, then it’s quality.

|April 2019||In July 2016 and an experiment to challenge himself as a writer, Jens launched a website about poetry; about haiku; about love haiku: Haiku Haiku Love. In 2019 Haiku Haiku Love features so many haiku, it’s ripe to share the best in a pretty book: 199 Love Haiku.|
I don’t know yet what to do with this page. It’s old and originates in times during which I was a little insecure and tried to prove myself.
Perhaps my most useful book: The Little Book of HTML/CSS Frameworks (2015). Why? Because only we know the needs of our projects, and because quality begins with these needs.
Perhaps my most interesting book: 100 Things I Learned as an Everyday Adventurer (2013). During my time in the States I started trying everything. Everything. Then I noticed that wasn’t only fun, it also brought many benefits.
