I can think of one easy one. If you surround a word with double square brackets in a blog entry, it automatically becomes a Wiki word that points to the Case wiki. So, if you typed something like:
Today, I walked around the Botanical Gardens and checked out the Art Museum.
Botanical Gardens and
Art Museum would automatically become links to the appropriate Wiki node once published.
What about Blackboard? As a matter of fact, I have heard that the administrators of Blackboard may be adding in the Learning Objects' Campus Pack plugin, which, in some fashion (it's hard to deduce from reading the documentation), offers blog and wiki functionality. How should all of that integrate together? Should it integrate together?
