I will most likely use the blogging and wiki aspects the most.  I do like the ichat, and I'm certain that this will become the norm within the district at some point in time.  I plan on using wiki for my Peaceful Playground items and some DA items.  I'm thinking about creating new wiki's for Central Activity Day.  Using this format to get all the info out to the parents about their responsibilities for that day and for the teachers so they know what, when, where, etc. for the day!
