Selling points:
Public humilation
En-mass sharing and in-depth discussion of links to pointless websites.
(1.3% of the WWW at time of publication - the other 98.7% are porn
sites with many points.)
Doesn't require declaration of allegiance to a Guild or quest
completion.
Go and post a new item with something interesting (or questionable) in
