I’ve noticed an interesting pattern on Slashdot. They’re notorious for duplicate stories (although, in my opinion, they have improved over the last few years). But a couple weeks after posting an article about a new Google feature, someone independently discovers it and the Slashdot editors feel the need to discuss it again. I only point this out because they did it not one month ago with search by numbers (original).
Update 25 Jul: Look, two more in the past 24 hours!
Update 26 Aug 2006: Another pair about Google Trends.
