It's frustrating for us though when you [USA] air your documentaries in Canada, and are quoting ounces, Fahrenheit, yards, etc.... it would be a nice gesture for us if you could at least subtitle the imperial measurements in metric
I've watched a fair number of the "How It's Made" series, an import from Canada to the US. The narration is apparently redone for the US market using Imperial measures, but the close captioning is original and keeps the metric units. It's amusing to hear the narrator say, "the stock is cut about every two inches" while the CC reads, "the stock is every 5cm".
As for myself, I only ever post to facebook via twitter (which also crossposts to buzz and livejournal).
Maybe that works for your friends, but I find tweets posted to FB and LJ are just irritating. Seeing the same tweets in both places is even worse.
Actually shark researchers have been observing Great Whites returning to the Farallon Islands about 35 miles west of the Golden Gate for over 20 years. This website doesn't talk about migration and return, but Susan Casey's book The Devil's Teeth does discuss how the researchers on the island saw many of the same sharks returning year after year.
The surprising things in the research (as opposed to the article) are the genetic distinction of the Hawaii-California sharks versus sharks in the Western Pacific, and to a lesser extent the fact that sharks habitually come close to shore but rarely interact with humans.
