I've noticed an annoying trend. Folks buy something from a site that allows product ratings. They post something like this after giving it 5 stars: "Bought the product, sure it will work fine". How the hell do you know?
This happens on gunboards and in gunrags a lot, too. I brought XYZ gun. Fired 50 rounds through it. FLAWLESS!!!111!!!!! BEST GUN EVER!!!111!!!!
And then two weeks later when someone asks about XYZ model of gun, the above guy and twenty other people who did the exact same thing jump in the thread with "XYZ is a great gun! Best gun ever! I've got 150 absolutely rounds through it. It's FLAWLESS!!11!!!!
BTW, can you tell I hate the term "flawless" with a passion now?
And then on the flip side, there are people who buy a product without researching it, expect it to give them the results they desire, and then when it doesn't live up to their expectations, give it one star. Even though the product performed to specifications and worked like it was supposed to. Instead of saying "This product works well, but because I did not research it enough, it did not meet my needs and I returned it for a product that does"
