"We're all teachers and we're all students," Dave Harry tells us. That's the premise behind a new site set to launch next week. The gated community will offer SEO experts a "comfortable" place to share tactics, strategy and, yes, even vent. The site, built and tested for "the search obsessed" by 100 initial members, offers a "private playground" to share and store resources, learn about SEO and discuss the daily grind.
