When designing the interaction with users it appears that long pages work. I agree with Peter Van Dijck. Some of the tech journals are really bad offenders. They break an article in to multiple pages and those pages are littered with advertising. Like Peter says. It makes you want to dive for the printer friendly page.
The bottom line - think about user frustration when designing layout and content.
Grayboxx is still in stealth mode but seems to be pioneering preferenceScoring to exploit the local search market. Their techniques look like they will tap in to sources of purchase data to generate recommendations for local retailers and service providers. It is an interesting tactic.
