Do you use Google's Calendar? I have been using it for some time now and, like most Google products, it rocks. My wife and I have integrated calendars on which we post all the exciting events of our lives like upcoming ice skating lessons, cub scout den meetings and pediatrician appointments. My 9 year old daughter even uses it.

Anyway, I am just amazed at how well Google has integrated the services of this calendar with their other offerings (like Search, iGoogle, Desktop and Maps) and how easy it is to get to your calendar from a variety of devices and interfaces. They now let you synch with Outlook. It even has a Calendar API!!http://www.google.com/googlecalendar/new.html

They could have built the calendar with basic functionality and left it at that. The calendar is very easy to use and it would have been considered a job well done. However, they just continue to refine and improve. Wouldn't it be nice if everyone's project could be carried through to full potential like Google does..?
