The document discusses how the WordPress open source project uses local meetup groups and annual WordCamp conferences to build community and overcome challenges of online communication. It notes that online communication can lead to "troll-like" behaviors due to anonymity and lack of in-person cues. However, the WordPress community coordinates its work through online discussions. The community has grown to include over 500 local meetup groups and over 750 WordCamps held in 65 countries. Bringing people together in person at these events helps make large-scale online collaboration possible.
