As an aspiring academic half way through a philosophy Ph. D., I find Nunberg's argument pretty absurd. Google books is a godsend for academics, and would be much more so if there was full access to their entire catalog rather than "limited previews" for most books. I have used Google books countless times to quickly check out whether a book is relevant to my research, or to get the gist of an author's argument without having to trudge down to the library. I know many others who do this as well. In all this time I've never even looked at Google's metadata. No decent academic would rely on such information, as there are far more reliable methods: such as actually checking what's written in the book, which yes, Google scans in.
I'm not sure what the legal mandate of the CBC actually is, but I don't think it should be to disseminate Canadian content. I think it should be to serve the Canadian public by broadcasting quality material that wouldn't necessarily be broadcast on commercial stations. Where that content is produced, and whether that content has a Canadian flag in the background or a shot of the CN Tower is of no interest to me. If the nationalistic agenda is undermining the quality content agenda (as I think it is), then something is wrong.
CBC Radio is great, but I think CBC TV would be a lot better if they didn't feel obligated to make all of these nationalistic TV series. I'm all for the government funding Canadian artists, but I hate content regulations.
