Postwaves allows anyone to create a public or private board for a community based around their interests or goals. Posts that are submitted are shown to a random cross section of the community to vote on, ensuring all posts have an equal chance of being seen. We've seen sites like Product Hunt build a community around products. Postwaves can allow anyone to create a community around anything at all, and ensure anyone joining that community will instantly have the same power as existing users.
