Acctually, i had my first collition yesterday.
Mootools and jquery had the same function that collided, so i thought id use jquerys compatability switch, but the plugin relied on using the standard way, so, eather rebuilt the plugin or find some mootools option. Spent 2 hours trying to find a mootools way of doing the same thing, ended up asking for it on the forums, got a RTFM and a UTS (Use The Search) got the thread closed. I only needed an Jquery portlets alternative for mootools!
I Want Jquery!
I think it´s wrong to assume that jquery is not for developers,
as Drupal has adapted it as the main tool. And to say that drupal people
are not real developers, are like spitting in alot of faces
Also, Jquery is already compatible with YUI EXT.
Why try to reinvent the wheel?
