Its hard to describe what twitnest is… you have to see it for yourself

At first the screen is a blank page and a simple login box.  Enter your Twitter username.  Then watch your nest gather.

• You can zoom in & out on the right side
• Drag anyone around to get a better idea of their connections
• See everyone that connects to each other
• Play with auto-groups (see below)
• Drag the page around to see more

You have types of modes in the bottom right.

• Mouse allows you to drag the page or items on the page
• Who knows whom lets you click someone and it darkens those not connected and highlights those connected
• Autogroup – this cool tool starts shrinking the communities into groups with a slider where you control the size and colors the icons for easier vision

This is an interesting tool that lets you see connections in a different way and visualize their connections
