This is so vague as to be utterly meaningless. So this is just a frequency chart of buzzwords seen on job postings?

It is a data point. Look at skills needed in dice or monster, look at tiobe.com look at languages on github and you get a picture of the fashion of the season. Most larger companies use keyword analysis to pick which resumes to look at. So if you use those keywords you have a better chance of finding a job. If you rather start your own company, of course it is meaningless.

What a bland list "technologies" ("Front End Development"?), and the post isn't really any better. I'm very suspicious that 3 people actually voted this up.

0.02: this is where the puck is. better get embedded, electronics and mechanical skills up to snuff if you want to be where the puck is gojng.
