When my brain is running idle, my hands autonomously type "Hacker News" in the address bar of my browser.
More like cmd+l (address bar), n (autocompletes to news.ycombinator.com), enter.
At least I'm getting efficient at bad habits ;-)
I do exactly that, but with a Ctrl + T first. :)
I tend to do it with complete lack of thought.
I'm also a cmd+l -> n -> enter guy
This procrastination is actually probably useful. If I go on other social networks the probably of usefulness or random items that an Algo targets me approaches zero
