The SciFi Channel website has launched SCIFIPEDIA, a science fiction wiki. Oddly, they didn’t grab the scifipedia.com domain name. Although I can’t seem to see the RSS feeds, other functionality is there, like categorized wiki browsing and This Day in History (on the main page). Like all wikis, content can be updated by anyone.
It’ll be interesting to see how this compares over time with Wikipedia which, right now, has way more content. As an example the Isaac Asimov Wikipedia enrty has much more information the Scifipedia Asimov entry.
