In 2005 Patrick Gruban, Julian Doepp and I founded sub-bavaria, a wiki-encyclopedia of the bavarian sub-culture. It used to be a very beautiful and successful wiki, e.g. it became the starting basis for the radio-campaigne Zündfunk retten! in 2006. Unfortunatelly it got attacked by spam in 2013. Since then some volunteers are trying to fix it. If you are interessted to support them: Help is always welcome. Just contact me.
