Web 4.0 "Good morning. You're flying to Boston today. Take a raincoat, it's raining. By the way, that flight you were taking, it’s already been cancelled. Don't worry about it. There was a mechanical. I've already booked you on a new one. I'll tell you about on the way to the airport. But remember you’re going to exercise every day and I’m here to remind you that you’re going to exercise.”

Policies of the Governments Key Issues Net Neutrality Policies of the Governments Security and Privacy

Policies of the Governments Google, Facebook, Twitter are banned in China (weibo) Indian Govt. Yet to make a strong stand on this issue Gender Determination Advertisements are banned in India

Security and Privacy Loss of Information (from web servers and phones) London Riots Visa Denial based on Social Media Usage Pattern CIBIL Rating Activities of USA’s NSA Edward Snowden, Julian Assange

Web belong to all of us!

Points to Ponder Gov. / Technology Companies / Agencies have to create policies for ensuring privacy Gov. should entertain constructive usage of technology Strong cyber laws to protect people Ethical / Personal change is the need of the hour How to keep myself safe? Pay cash for everything! Never go online! Don’t use a mobile phone! Never leave your house! 
