Erik Möller or Erik Moeller for those who have a problem writing a foreign name is a longtime friend. I worked with him often particularly in those days when wearing a ponytail was en vogue among geeks.
The one thing I savour in this blog post is that I am not writing because of Erik passing away; it is only that his days at the Wikimedia Foundation are numbered. It has a bitter sweet ring to it because I know how much the WMF means to him.
We worked together on Wikiprotein and OmegaWiki. Sadly at the time the Wikimedia Foundation did not want to adopt OmegaWiki because it was too expensive at the time. In the mean time OmegaWiki still has an edge in several areas over Wikidata but in the one area that matters it does not. There is even a publication with our name on it and Jimmy's..
Erik I expect that you will have fun.
