The problem with the OER Commons stuff is the same problem I have with site like Curriki. It needs a lot of “gardening” to improve the quality. Both have a lot of mis-indexing (e.g. graduate courses labeled as “primary”), content that is not really “open” (e.g. traditional copyrighted materials), and links to web sites that are not really learning resources.

I’m sure that things will get better though as more people work on this.
