I have been editing Wikipedia since 2003. Recent changes and my watchlist seem to consume most of my mainspace time, but I also enjoy piecemeal additions of well-referenced information.


I have long appreciated the Signpost, the English Wikipedia's community-edited weekly newspaper (having commended its journalist values as early as 2005 during a discussion on de:). I started contributing to the Signpost myself in 2009, and from June 2010 to July 2011 acted as its editor-in-chief. I still edit its monthly report on recent academic research about Wikipedia, which is also published separately as the Wikimedia Research Newsletter, and co-edit the associated @WikiResearch Twitter feed.

From 2011 to 2019 I worked for the Wikimedia Foundation, most recently as a senior data analyst.

I was known as "User:High on a tree" from December 2003 to June 2008, when I changed my user name to "HaeB" ("High on a tree" initialismized in German) for consistency with my nick on de:, and to save bandwidth ;-)

I was a CheckUser on de: from July 2006 until October 2011 (I decided not to run for reelection after starting to work for WMF). I am also active on Commons.
