I have some reservations to people saying that $8mn is too large an investment on Qwiki. $8mn is a serious commitment and they don't invest that kind of money unless they see some real spunk in the idea and the team. Perhaps what QWiki has built is an infra layer designed to add scale to their effort. I have been an alpha user on Qwiki for sometime now and they manage to pull me back to their site with very interesting mailers - Qwiki of the day - which is not a trivial accomplishment imo, if they are doing it for a lot of their users.

Plus, as an application, the real power of QWiki isn't on the web - its on the mobile/tablets, particularly in education. Qwiki is in a great position to replace wikipedia as a quick intro to any topic for millions of students round the world - that itself is an interesting usecase for me - and they are achieveing this through technology...
