What is the difference between a group, space, blog and monitor?

Spaces, blogs and monitors are all types of a group. These are the main differences between them:

• A space is for collaboration between a number of different people. They can use instant messaging, email discussion messages and share knowledge entries, as well as view news feeds that the space is subscribed to.
• A blog is more for broadcasting information to a group. Members of the blog may also be able to respond to blog posts with their own comments.
• A monitor brings in information sources from outside where they can be read by members and the information analysed.

A user's status updates are also part of a special group that is created behind-the-scenes when they write their first update.
