Trendsetting is Dead
With the growth of collaboration online, the death of the trendsetting profession may be near. With search engines tracking popular searches and weblogs giving everyone a voice, it's not too hard to figure out what's in and what's out.
All of this may be the demise of cool. A big ingredient to something being cool is its under the radar factor. Once everyone knows about it, it's not cool anymore and the length of time between cool and uncool is fast decreasing. Very soon we will reach the point where nothing (and everything) will be cool (or not) at the same time.
