I know it’s probably way too late in the release cycle to add another section, but if you can, in “The Web, v2.0” it would be invaluable to have a section on using jquery instead of prototype.
jquery has been picked up by numerous big organisations - even microsoft. It is IMHO much much cleaner than prototype syntax. Just search on google for “Jquery vs. prototype” for a plethora of reasons why.
Every web designer I know prefers it, and it would be a great way to show off the flexability of rails.
Even some links to some sites or a quick pointer on where to start would be great.
