The wiki is a great way to commute with other people, if you know how to use it. You should at least one day a week make the students go on wiki mail and commute with other wikis. If you have a project, set it up on the wiki. Make pages about stuff you like, learned, or have done and make them detailed or important. This year on wiki I would have liked to commute with other people, but I did not have time. It was good, no great all in all through the year. My goal for next year is to commute more.
