Jake at CenterNetworks does a video review of Stikkit.  Its a highly intelligent web 2.0 application, and the way it handles dates, to-do’s and tags is quite remarkable.  It takes natural typing and interprets them. 

For those of you who don’t know, Stikkit is a really cool way to keep track of everything, whether it be appointments, meetings, to-do lists, or people. Stikkit does it all, it was really cool to look at, and I highly recommend this app to get you on track with your life!

It incorporates automated linking to the usual calendar formats, so in essence Stikkit becomes your interface into your normal workflow. 

Its a great example of how things can work for the next level of web applications.
