I've found that creating a learning "space" to work within on the filesystem is an effective way of being able to use commands, watch their effects and do it with a lower risk of unintended consequences.
Ha! I've encouraged such in prior articles and have even given people files to download and use to explore.
Those articles get read thousands of times and maybe 3 people download the example file.
(I do sometimes have folks make special directories to play with, and then tell 'em how to clean up the mess after that. I haven't done so lately as I figure about the same percentage of people are going to do that.)
I'm lucky if I can keep their attention for more than 3 minutes. They skip the intro and ignore the closure.
I did heat maps for the longest time, until just about a week ago. I used Clarity from Microsoft to track (unknown) individuals through the site. It didn't identify anyone, but let me track individuals (and trends).
Heck, want some 'proof'? Search the site for the word 'charity', which was one of my ways of testing how accurate the heat tracking was. Feel free to claim the prize. That article has been "read" many hundreds of times.
Also, the scary part (or perhaps sad, or amazing) is that getting 3 minutes of their attention puts my site above average. It's well above average.
I'm gonna actually go be productive in the snow (shortly, I'll check the posts first). I'd love a glass of wine, but I'll be driving a big ol' plow truck with a thousand pounds of sand in the back. Gotta be sober for this sort of stuff, but it sure is fun!
