Yess, and a local Facebook group and/or subreddit can work really nicely in coordination with a LocalWiki. To share local knowledge you totally need that conversation part, where the oldtimers and newcomers sit around and chat (or comment) about what's interesting today and what happened a while ago, in a casual and amusing and timely way. But then you also need the reference part, where bits and pieces slowly get collected and organized and cross-linked to tell a more comprehensive story, and to make sure individual memories don't get lost if people move out of town (or get busy, or die) and aren't around to tell their stories anymore.
