Zoho Notebook

As written in ReadWriteWeb, "With Zoho Notebook, you can create many different types of content - such as text, image, audio, video, drawings, RSS feeds. It's also a content aggregator (including HTML content from web, Zoho Writer doc, Zoho Sheet spreadsheet etc) and has impressive collaboration features. While content aggregation and collaboration are almost mandatory these days in a Web Office product, it's the variety of content you can aggregate and collaborate over that is impressive in Zoho Notebook." Zoho Notebook is really one perfect online product. It's valuable to try out.

I made one "twitter page", and share it http://notebook.zoho.com/nb/public/terababy/page/2880000000003129
