Backpage is getting popularity

As posting on craigslist is becoming tougher day by day people are now switching to backpage.com to post their ads.
The backpage site is growing at an average rate of 21% per month. (source: About Backpage.com)
Beside craigslist Backpage is the only free classified site I have found which support a wide variety of HTML elements in description.
Backpage has significant popularity in the USA. It has only 3 Canadian cities. No cities from any other countries yet.
Backpage allows renewal of the old ads after 30 days.
