"Google" - A search engine that is better than others because it doesn't rely on keyword frequency but rather other sites that reference it.
"Facebook" - A social network that relies on exclusivity through both signup and connecting to others to engage customers. Stickiness is applied via user's updating their status, linking to sites or subjects of interest, discussing upcoming local events, and various methods of social graphing (i.e., how users are connected to the people they want to connect to and the people those connections are connected to).
"Wikipedia" - An online encyclopedia that is created, edited, modified, and updated by Everyone. Accuracy is mostly preserved by off-page discussion and off-site citation. It's goal will be a recreation of the Library of Alexandria [<-- that's the stinger selling point.]
