Seems like the choice is between implementing this feature sooner or later, since it will eventually be mandatory. Discussions don't look terribly different or less easy to use than the existing Forums, and since participating in the social aspect of wikis is optional, it's hard to come up with any downsides to setting up Discussions now.
