That is technically true, though in practice the definition I believe has expanded to include "general news and press coverage of XYZ", which is how I'm phrasing it here.
Having had some work get incredible attention, and other work not at all, I've experienced a small slice of the volatility of the web. My most popular, for example, tweet chain was a semi-technical vent I wrote over the course of 30 minutes after stewing about some semi-useless technical hype that no one seemed to be addressing the flaws in. I wrote it in a way that was more attention-grabbing somewhat than my more technical posts, put it out there, and shared it in a few places. It was pretty shallow, technically, I think, but I feel like it really had to be stated, since it sorta felt...really pretty obvious?
Two days later or so, my number of Twitter followers had over quadrupled.
I think humanity can be quite finicky sometimes (a more general statement, I don't think one could conclude that from the previous anecdote alone).
