:) In that sense some of my activities on the startup scene are pretty practical:

http://garage48.org/ - we organize weekend startup bootcamps in Europe and Africa, hopefully having 6+ events in 2011 across Africa. Our goal is to get people into weekend projects, then into startups, then growing out from that "lifestyle" into large world-changing companies.

http://hub.garage48.org/ - co-working space for startups in Estonia.

http://opencoffeetallinn.com/ - OpenCoffee Club Tallinn.

http://startupleadersclub.com/ - Estonian Startup Leaders Club.

They all share the same goal: more startups means more developing economy. The lifestyle is just the patch of reaching that.
