I know a few people whom keep up on tech trends, even though it has nothing to do with their job.
I follow programming trends, basically through HN, and self study. (I have wasted a lot of money on programming/Computing books.), and I'm basically a Jack of all Trades in life.
I'm a mechanic certain years. I'm a contractor certain years. I'm a Electrician when I am very low on money. I'm a Watchmaker whenever someone asks me what I do. (I hate that last sociatial question. When did it become copacetic to ask for job status, and finances. I guess it came with the Selfie. (I didn't use a question mark on purpose. Too disenfranchised today to care.)
I do miss the days before relying on bloated JS libraries.
I miss the LAMP days for my personal websites.
There was a free server I used to use, but forget it's name.
It allowed full domain names without their branding. Like mysite.com, instead of mysite.com.branding.
I know Git, Google, and Amazon offer a free page, but I just don't like learning their way of putting up a site.
As you can by my verbage, I'm not a professional.
But for some reason I try to stay current on certain aspects of this industry.
