Here’s a quick poll. Our project will develop a plugin for BuddyPress that allows academics to connect their BuddyPress profile to third-party websites where they host their OERs and display those resources on their BuddyPress profile. Sites like YouTube, Scribd, Slideshare and Jorum seem like popular choices. There are a lot of these services and we need to prioritise which ones we work on first. Help us decide by completing this short poll.
Feel free to ask questions or leave comments below. Thank you!

YouTube has CC licensing: https://www.youtube.com/t/creative_commons
and downloads: https://support.google.com/youtube/bin/answer.py?hl=en-GB&answer=56100
which makes it an OER platform in my book.
Thanks for the other recommendations. We’ll add them to the list.
Youtube OERs? Not sure Youtube has any properly cc licensed stuff?
Also, cough, Xpert has a CC API http://www.nottingham.ac.uk/xpert/labs/
I’d also look to merlot and oer commons (we have basic wordpress widgets for these)
