An advertising blurb that led me to the site:

Curl up with some “bright ideas” this weekend: We’re pleased to announce the launch of a brand new resource for Canadian higher education: the Eduvation IdeaBank. Browse 50 of my favourite innovations in higher ed pedagogy, marketing, revenue-generation and student services. Comment, vote, or submit some bright ideas of your own! Check it out at www.eduvation.ca/ideas

I'm sure there are multiple motives for the site. The authors receive fodder for their (his) other activities probably being the largest. That does not preclude its usefulness as a source of, and forum for the discussion of, education related ideas. I was really excited when I read the encouragement to "refine" ideas as I was picturing a wiki like ability to edit - refinement however is relegated to the commenting capabilities. The ability to "Like" ideas gives it some usefulness as a socially built recommendation site as well as just a place to view and discuss ideas. Considering that the "Most Liked Idea" only has 4 votes though leads me to believe that this is very early in the cycle (which might be a good thing depending on your point of view towards the wisdom of the crowd).
