In the absence of large established transhumanist forums, the largest transhumanist and futurist groups that exist are on Facebook. Facebook links associated with specific organisations covered on H+Pedia should be linked from their respective pages.
CEO Mark Zuckerberg is a life extensionist and probable transhumanist.
Many transhumanists are using Facebook heavily for networking and advertising. The hashtag #transhumanism is sometimes used here as well as on Twitter.
The largest concentrations of transhumanists can be found on facebook groups, and there are also many popular news pages to be found.
