Here is something interesting:
Number of listings in 2009 shows steady rise of approx 1.24x in 5 months (= 4.4% per month or 53% per year).
Number of pageviews drops by 1.4x in last 21 months (approx 20% drop per year):
20% fewer pageview over 50% more listings means 80% less marketing value for given listing fees amount comparing now and year ago.
Ouch!
