Web 1.0: Browser as Paper

Web 2.0: Browser As Platform

A Dramatic Transition

People expect less online.

But we are online

and tied to the browser.

So we must level the playing field.http://www.flickr.com/photos/probek/44480413/

how?

it takes 2 thingshttp://flickr.com/photos/latitudes/104286031/

We mustimprove our technology

(we need a robust platform!)

andraise expectations

(so users engage and explore with confidence!)

Nuts and Bolts http://flickr.com/photos/snood/129758197/

Six commitments to the platform

1] Meet properties where they are today. Facilitate incremental enhancement(Transitional Internet Applications)

2] Provide a broad, inclusive platform for Web 2.0s Rich Internet Application development(a la carte, not framework)

3] Extensible and adaptive, to meet the needs of our diverse product portfolio(lots of different contexts)

4] Support all A-grade browsers an evolving and still demanding challenge(Graded Browser Support) http://developer.yahoo.com/yui/articles/gbs/gbs.html

5] Support our scale and scope (industrial grade)

6] Be responsive and accountable to our community of designers and engineers(your P1 bugs are our P1 bugs)

Beware!Good experiences arent plugged in

they are crafted by thinking about people, NOT by thinking about technology

Developers can provide powerful primitives and compounds

but designers create idioms and love
