Hi Piotr,

I do not have much personal experience other than running into some inspiring articles here and there and noting the journals that have published them. I would get in contact with Dan Cohen, <dan@dancohen.org>, the Director of the Center for History and New Media at George Mason University. They are very Wikipedia-friendly there (they are also who originated THATcamp) and are a strong presence in the digital humanities field. He may have some more specific help for you.
