How to improve the 360

The new xbox experience is cool and to take it to the next level ms should be even more asynchronous. Have a new system called events that people can setup and invite their friends who can then accept or decline. If a certain threshold accept then the event is scheduled.

Also you should be able to invite people who are not online through integrated text messaging.

Also to help out games that have a low online player base they should publish when are the best times to play the game.
