I've noticed that there seems to be a growing competition between Wiki and SharePoint. It seems like there are a lot of teams out there trying to decide how to handle internal communications and collaboration, and Wiki and SharePoint have become the top options for teams that want to go beyond just e-mail. I've used both of them and I think Wiki is great for sharing ideas, compiling meeting notes, and some basic project management tracking. I think SharePoint is better for group calendaring, sharing and collaborating on documents, and organizing annoucements, links, and other text. I've started a new discussion thread on this topic.
