Guess we are married for too long, I remembered only when the bank called Swati and told that the client’s payment has come in… been playing around with the Yahoo! UI Library it is pretty cool but I do not think that we are going to drop what we already use, the Y! library is about 8 months too late. Besides, it does not have anything drastically new in terms of widgets or for that matter ease of programming.
But if you happen to have lived beneath some rock till now and have not tried your hand at the so called *web2.0* (I hate that phrase) you can start with this one – lots of documentation available.
BTW, if you happen love AJAX (damn! another buzzword) but hate to do all DOM rewriting manually and further hate writing JS in your PHP or vice versa – try out http://taconite.sf.net
