I was a visiting scholar at HLS for 2011-2012 from Kozminski University (Poland). I've been a Wikipedian since 2006 on Polish Wikipedia (where I'm an admin, bureaucrat, and a mediator), occasionally editing on other projects, too. Till February 2012 I served on the Wikimedia Ombudsman Commission, and I am currently a steward.
I wrote an ethnographic book of Wikipedia community from a participative perspective, it is currently under review at SUP.
