Here's an interesting set of new mashups, all three quite visual: visualize the relationship with your friends, get a map-centric view of Twitter activity, and make Skype more visual by integrating web maps.
- Friend Explorer: Relationship visualization mashup. Graph your Facebook friends and their connections to each other.
- Twitter Atlas: Most recently posted Twitters locations plotted on a map and updated automatically. Slick interface built using the Virtual Earth and Twitter APIs
- Unype: Use your existing Skype account to connect to your friends in Google Earth and take them along with you. When you move in Google Earth on your computer, your friend moves in Google Earth in real time on his or her computer.
