Why is it that the worst things always become the most popular? I mined my first bitcoin before it hit a dollar, so it's nothing against bitcoin, just as acknowledgement of the ridiculousness of the trend of cloud computing is nothing against the cloud itself. Why can't we get a fad that's reasonable for once? I just don't get how people convert these specialized things that may help some companies sometimes into widespread hysteria, where every company feels like they have to go all in. Companies regularly take their basically-fine hardware offline so they can start renting the same or worse from Amazon, because then they can tell people that they're "in the cloud". I know one company that used to have all their stuff running on hardware and working pretty much fine. They switched to "the cloud" because they thought it was cool. They now pay Amazon the amount of money it'd take to re-buy all the hardware that used to run their site each and every month. I should figure this out because if I can see one of these trends coming and time it right I could make a lot of money.
