One of the things that Amazon.com is known for is their recommendation engine. They look at your past purchases, items you've recently browsed, items you've reviewed and so much more to recommend other purchases to you. This concept really works in the favor of both the consumer and Amazon.com. They get more sales and we get products that make sense for us. Win, win.
I noticed today when visiting Amazon.com that they had some new suggested items for me. I viewed a gyroscopic air mouse the other day and this is what they are now telling me:

I looked at a $150 mouse for my computer and I should now look at a case of PowerBar's and an electric razor? Come on Amazon.com, it wouldn't be that hard to limit this type of recommendation to at least the same general category!
I have a bunch of other ideas on how Amazon.com can further improve their recommendation engine but I'll save them for another blog post (or for when they hire me).
