The PBWiki (short for Peanut Butter Wiki) which hosts BarCamp site and facilitates collaboration for most of the BarCamps across the world has crossed the 50,000 wiki-mark. This makes PBWiki “the largest consumer wiki farm” on the planet.
PBWiki is a part of Coceve, a privately held company in the Bay area, and is run by 3 Stanford graduates.
One really heartening fact is the person leading the marketing efforts is a person of Indian origin. He is Ramit Sethi, creator of a very popular iwillteachyoutoberich. As per Ramit’s bio the blog hosts over 100,000 users per month.
