Where's the heat?

Is that your goal? To find the next hot thing? Do you want to buy it, sell it, use it, eat it?

In every industry where there's fashion (which is every industry), people spend an enormous amount of time looking for heat. It defines the cutting edge, determines what's in or out, what's hot or not.

Two things worth considering:

a. the hot thing isn't always the thing that's aligned with your goals. Sure, sometimes the most profitable item is also the hot item of the moment, but for many companies, market share or profitability or utility has not a lot to do with being on the cutting edge of fashion. And as a user, the hot item of the moment isn't necessarily the thing that will create value or even identify you as truly hip.

b. The cycle of hot keeps getting shorter.

You can chase this, but it's not free, and it might not get you where you want to go.
