There is an old saying that “Birds of a feather flock together”. The Birds of a feather sessions are a regular feature at FOSS4G conferences, and are an opportunity for like-minded people to informally gather and discuss their interests.
These could be groups linked by particular software, by geographical area, by language (human or computer), or any other aspect of free and open source geospatial.
We’ll provide some rooms for this self-organizing gatherings. Use the OSGeo mailing lists(email@example.com) for discussions, and check out the Birds-Of-A-Feather wiki page for current plans or to make your own first.
