The future：Web2.0, Web3.0, WebOS

“We are seeing that manifest in Web 2.0 and 3.0 will be a great extension of that, a true communal medium…the distinction between professional, semi-professional and consumers will get blurred, creating a network effect of business and applications.”

Jerry Yang, Yahoo CEO, Nov 2006

The future of web – Web OS, Platform

• WebOS and Web operating system"the emergent Internet operating system" as an open collection of Web services.

» April 2002, Tim O'Reilly

• PlatformA "platform" is a system that can be programmed and therefore customized by outside developers, users and in that way, adapted to countless needs and niches that the platform's original developers could not have possibly contemplated, much less had time to accommodate.

» Marc Andreessen


The future of web – Web OS, Platform

• More Web Apps are for the social networks– People relationship/space– Myspace.com, facebook.com, Hi5.com– Wealink.com, Xing.com, Linkedin.com

• More Web apps will use the services from giants (Google, Yahoo, Microsoft, Amazon)– They will buy the greatest websites.


The functions of Web OS / Platform


There are four types social network


What we will do?

• 1. Get Users (= Acquisition, Referral)• 2. Drive Usage (= Activation, Retention)• 3. Make Money (= Revenue)


What will we do? The Metrics Model


Why use ruby on rails？

• Less code, easier maintenance– Less and more readable code– Almost no config files, predefined directory structure,

naming conventions. It let’s you write beautiful code by favoring convention over configuration.

• Agile– shorter development times, simple but powerful, no

compilation cycle– Best practices: MVC, DRY, Testing– Integrated AJAX support. Web services with REST.

• Open source, good community– Good community, tools, and documentation


Why use ruby on rails？

• Happy– Optimized for programmer happiness and

sustainable productivity.• Successful stories

Our strategy for the new website - Systems

• Search engine– Tag based, (tag, Index, abstractions)

• External Web Services integrated – ADSense, Video, RSS for blogs.

What’s kind of people we need？

• Creativity, passion, incredible technical ability, and a drive to build interesting things.

• Creative enough to have built cool things on their own

languages you know right now.
