Structure of the Web: Hubs and Authorities.

Jon Kleinberg of Cornell University characterized the Web in terms of hubs and authorities (and in terms of density of links among pages) in order to define the structure of the Internet:

According to Kleinberg and Lawrence, a hub is page that points to many authorities, whereas an authority is a page that is pointed to by many hubs (left). An alternative method to identify communities is to look for nodes for which the link density is greater among members than between members and the rest of the network (right).

I wonder if Neatorama a hub or an authority? It links to *a lot* of websites, but it is also linked by a lot of them …
