A few weeks ago the Travellr.com ‘questions and answers’ website was pottering along, a bit of traffic and content, nothing special, still struggling to gain true traction after a couple of years.

It feels alive. The site is now claiming 19,000 members from 126 countries. What a difference an App can make.
