I first expected a "screen -x" tutorial (which attaches multiple clients to the same session; screen sharing, if you will) when skimming HN titles, but yeah the "by the cofounder of X" tipped me off when I read a little closer. Going to be hard to google, though. For reasons unrelated to GNU screen, I dislike product names that appear in a dictionary with the most common words. Not saying that /screen would be a bad Slack alias or whatever, so long as that isn't taken why not, but as a product name there might be a nice thing to tack on that you can abbreviate to Screen but still allows you to google for the right thing or clarify when someone is confused.
