I suggest using Blogger, because using a Wiki might be fun and all, but you have to spend all that time getting to know a whole new framework, whereas we're all familiar with Blogger. The trick is to design it in such a way that we can simulate the communities, and we can have a pseudo Friends page by having everyone publish their journal entries to a Journal account.
