web2.0 apps

Well I have been looking at a couple of web apps to help sort my biz. I have been using three web applications, not counting blogger, gmail and flickr.

www.calendarhub.com great little calendar program. exports as ical for use in other apps. www.writely.com a web2 word processor. exports as html rtf and soon pdf too. Easy to use also. www.voo2do.com this is a todo list system. im just using the baics but it looks ok. It needs to be tied into the calendar. But is great for getting down the ideas the come to me.

Best of all with these applications, all the data is online. I don't mind the privacy issues and I love that if my computer dies, i don't loose my data due to not having a backup.
Just to see how the idea of online documents can work.
