That this audience and 37Signal's audience scroll doesn't mean that Paddy's point is correct. The rule of thumb is really about making sure you look after "regular" users.<p>I'd love to see the "below the fold" rule disproved, however the fact that Google and Yahoo! search engines still deliver a default 10 results with pagination suggests to me that most people don't scroll, still. When it comes down to it Google and Yahoo! test more than anyone and there is real money on the line there. They would increase the default number of results if it made sense to do so now.
