There are few tools in the world that may be quite simple yet innovative. In my opinion, Etherpad is a very useful tool that can be used as the means of collaboration on a text document in a real time. The official site describes Etherpad as

The perfect way to collaborate on a text document and keep everyone literally on the same page.

Like popular micro-blogging platform Twitter, Etherpad is also quite simple but innovative. I am wondering where was this tool before. People talk about various online collaboration tools like Google Docs, Zoho and so on. But non of them are as simple as Etherpad.

After creating new pad by clicking “Create New Pad” invite other uses either by sending the link of the pad through IM or email and start to collaborate as never before. One can also chat in the same document.

I really like this simple yet powerful concept of Etherpad. Isn’t this a great tool?
