Asked about traction, Korevec confirmed the number the hosts had on hand.
"It's been huge." — Kath Korevec

John Coogan described building dozens of Sites himself, including one that pulled a Zillow listing, restyled the photos to show what a remodeled version of a house might look like, and then priced out the renovation using neighborhood comps. He said he eventually built a "meta site" just to organize all the sites he'd made.
