There was a story about david and goliath in web 2.0 term. Aint no talking about dirty game,or fraud in web usability.Battle between O’Reilly and Webguild. Is not about right or wrong. Moral of the story.When Company build community in open source, they should not cut off support.They should be full support.Cause open source is not free,but without support we’re nothing. So Community is power.

What if Tim O’Reilly do tricky business ??, suing non-profits and do someone else his dirty work.Web 2.0, is the free flow of information, however …

Well i’m a dummies, try easy solution to get clear with ajax. So many solution here.Opensource is power,but lack some documentations and examples. Good ajax framework here : EXTJS and jQuery.
Grid: Extjs is good choice,but too complex for beginer, you can choose jQuery..maybe it more easier..
Just my humble opinions..
Good Links :
Extjs : www.extjs.com
jQuery : www.jquery.com
