Portlanders do communities.
Here are some that make this town special:
Calagator "World Class" If you want to know what's happening in Open Source in Portland Oregon: Start here. Return Often. A unified calendar for the technology communities in Portland.
Silicon Florist Covering the blossoming startup industry in Portland, Oregon, and the Silicon Forest
Free Geek "World Class" Technology recycling organization, takes in old computer equipment, finds new life for most, recycles items past their useful life. Cool used hardware store.
NedSpace Co-working for startups, tech companies, designers, programmers, nonprofits, remote workers and social entrepreneurs.
Columbia Gorge Model Railroad Club"World Class" Large indoor electric train set. One of the sites used in the making of the movie - Train Master. The club owns their own building. See a 60' x 70' room, full of model trains.
Open Source is an ecosystem and a way of life. It's not just about software.
"World Class" is just our Not So Humble Opinion. YMMV
