Yahoo! have a bit of a lame history. They were given many millions of dollars and have always been one of the most visited websites on the internet but somehow they have never really done anything that exciting with it.
Recently that has changed. There was the Yahoo UI Library which made AJAX programming much easier and is supposedly a really awesome tool. Their new tool I’ve been playing with is Yahoo! Widgets. It rocks. It seems to be what google was going for with google desktop but its infinitely more useful and comes out of the box with much cooler tools. Nothing too amazing – I’m using it for weather, RSS, calendaring, email checking and todo list but its just a really nice looking dashboard and if I’m going to be looking at my computer all day it may as well look nice.
