Well I was reading the Google articles in this month’s Wired and I found some pretty interesting things. As I read here, Google has a lot of things up their sleeves, one of the most interesting is Banana Slug. Basically, Banana Slug is Google with a twist; It adds an extra word onto your search to give you some very odd results. Go ahead, try it out.
Wired also has a very good article on content spammers and what measures are being taken to keep them from gaining PageRank. You can read it here.
