The three are Google Docs, Buzzword, and Microsoft Office Live.

Google Docs

I feel that it's really handy. I write documents everyday using it. It supports document, spreadsheet, and presentation now. I can easily write something from scratch, then publish them out in real time. Moreover, it's able for people to work on the same documents or even projects together with colleagues or partners in different locations. One of the best features I like is that Google Docs stores and organizes my work online; thus I can access and edit them from anywhere. With search feature, it's easy to find the exact documents I want. Today, I suddenly found that I was able to create folders under folder—it began to support subfolder—which I had been looking forward to for a long time. Google is not the only one that offers online document collaborative editing applications, but definitely it's the most to me. I love it so much.

Buzzword

I knew it recently. As Adobe's new online word editor, it's being backed up by Adobe for the moment. It's flash based, so it's cooler than others, but it needs much time to load applications completely (probably I live in China Mainland). I really likes its UI, that menus slide in and out smoothly, and editing interface is intuitive. It's a bit rudimentary compared to desktop word processors, but for an online collaborative tool, it's pretty sweet. Also you can share your documents and collaborate with others on it.

Many things I likes about it, but I didn't use it much. If you want to have a quick look at it, go there and sign up.

Microsoft Office Live

Microsoft has been chasing the "Live" idea for a long time and released a series of products, such as Microsoft Live Message, Live Space, Live Storage, and now Office live. I like Microsoft Office 2007 very much, especially its Ribbon UI which is optimized for efficiency and flexibility. Now, there is an online extension of Microsoft Office called Office Live, where you could store all of your office documents online and share them with others easily. From this post, I knew that Office Live Workspace is still in beta and is not available to the public just yet. But as I learned from the post, Office Live Workplace is simply a place where you can share documents with others, add notes and lists; it's not a place you can edit or work on them online as you can in Google Docs. Probably it's hard to support as rich editing features as desktop software in browsers, thereby they do not provide any. It is not that useful if you must have a local desktop copy of Office package on your computer.
