When something leaves the world, something new is born! Web 2.0 is soon going to be replaced with its smarter sibling i.e. Web 3.0; overcoming the issues of security and privacy.
Instead of insecure databases and opaque data sharing practices, Web 3.0 will return control to the users which mean they will be able to access data from anywhere; mainly being driven by cloud applications and smart-phones. Apart from security, personalization is another add-on!
