Pageflakes is developed using ASP.NET 2.0 and Microsoft Atlas.
Here's what Pageflakes say:
Pageflakes is your personalized Internet. You can add what you like and remove what you don't like - and it's totally simple. What you see on the site right now is just a selection of a few standard modules ("flakes", as we call them) that allow you to read blogs, do web searches, create a to-do list, check your Gmail account and read the latest news. Normally you'd have to go to a different web page for each of those things. With Pageflakes, you have it all on one page! And it's all free.
Note: You can now create public sites and share your page with your friends! Setup a personal site very easily and collaboratively work together
