And a substantial amount of the material that is there is bizarre content that's unlikely to be useful to teachers or researchers -- for example, the site hosts "courses" for topics such as "Dominant group", "Intentional Evolution", "Finding Courage", and "ACR" ("Action + Circumstances → Reaction").

Without pointing any fingers, I get the feeling that a substantial amount of the content on the site is the work of a couple of users treating the site as their personal blog, rather than an attempt to build content as a community. There's very little visible collaboration.
