MindMeister

What it is

MindMeister.com brings the concept of mind mapping on the web, using its facilities for real-time collaboration to allow truly global brainstorming sessions. Users can create, manage and share mind maps online and access them anytime, from anywhere. In brainstorming mode, fellow MindMeisters from around the world (or just in different rooms) can simultaneously work on the same mind map and see each other's changes as they happen.

Why it's cool
MindMeister gives people the opportunity to create concepts by mind mapping and brainstorming together, but not having to be on the same place. This is a great way to connect, for big international companies who want to share their ideas.
It will save time but also a lot of burnt gases because businessmen don't have to fly any more when they have a creative meeting, so it's also a eco-friendly solution. This is a trend manifestation of the trend globalization but it seems also adapted to web 2.0, stress society and sustainability.
A great concept which will that brings al lot of positive things with it.
