General groups

General discussion group

Created in May 2014 as an experiment. Not used yet, but feel free to use them for whatever purpose you think valuable. It’d almost always make sense to also put posts sent to these up on the Facebook EA group, but cross-posting to them ensures that most people on their lists will see your post (via email notification).


Private but non-confidential groups

EA Prediction markets

Frequently asked questions

It's worth consulting the FAQ which links to prior discussions of topics. It's best to comment on this old discussion - unlike in some non-EA groups, resurrecting old threads is fine, and preferred to covering the same ground in new ones. This applies especially on the main EA Facebook group, which has high volume. Most other groups have lower volume, so don't be put off posting there by concerns about making the number of new posts too high.

Suggested principles for what to post where

Tom Ash and Peter Hurford came up with the following suggested principles for where to post stuff:

* Effective Altruism Forum -- http://www.effective-altruism.com -- polished posts of good relevance to the EA community

* The EA Facebook group -- https://www.facebook.com/groups/effective.altruists/ -- links and shorter questions or observations, which can get discussed by a broad range of people. If the Forum is analogous to LessWrong Main, the FB group is analogous to LessWrong Discussion.

* The EA wiki -- effective-altruism.wikia.com -- collaborative articles and pieces which are descriptive rather than containing your personal perspective

* .impact wiki -- http://impact.hackpad.com -- Meeting notes and project updates for .impact

* Impact Research -- http://impactresearch.hackpad.com -- unpolished or not very relevant posts
