Another test case: I pasted a couple paragraphs of John Gruber's Kindle review in there, and it shows me (only) "Fleetwood Mac" (derived from the phrase "my Mac"), and "I Love" (the country music song, from the sentence "I love glowing screens"). It skipped terms that seem to me much more obvious links, like "iPhone", "iPad", "TiVo", "ATM", "Kindle", "credit card", "supermarket", or "e-ink".
