A strange thing about the Amazon recommendation system – it’s retarded.
It may make sense, in the context of books or music, to suggest you might be interested in something similar to a previously purchased item. But, in the context of technology, it’s just bizarre. “Hey, we noticed you own a wifi card, so you might be interested in another wifi card.” Um, yeah. Thanks, got one. “You purchased a couple books on Microsoft Access, maybe you’d like all the other books on Access ever published.” Why would I?
And don’t even get me started on the way that different editions of the same book or CD get hawked, after I purchased one already. “You bought Depeche Mode’s Songs of Faith and Devotion, maybe you’d like Songs of Faith and Devotion [Enhanced]?” Seems unlikely, doesn’t it?
