What I learnt?
* You need to sell your service to the whole world. Identify a little group of people - and show them your service, tell them your story - they will spread the word for you - if they like it and your service is good.
* Everything starts small - as a seed, as a nucleus. Hold on tight to it - and start developing on it - working around it and slowly let it evolve. Much like the agile process that I follow - in many iterations - adapting and modifying according to the feedback and what the customer wants.
