The lady doth protest too much, no? The guy is using Redis as a buffer to what ultimately ends up just being a central log file. You know. rsyslog. None of the fancy things you have in mind. Which brings me to the same point someone's already made: using Redis buys you nothing, even if you had a more involved use case in mind.

Saying that he can do something by subscribing to an event in Redis is sorta silly, isn't it? You could just as easily tail the logs, as many systems actually built for this purpose do. Once again, there are already things in *nix for this.

The reality is, this is a janky, nubile solution to an already well-solved problem that is now getting thousands of views because of HN and antirez tweeting about it. Instead of learning the correct way of doing things, I bet a bunch of inexperienced developers are now going to say "BOY THIS IS SWELL" and cut themselves a nice fat chunk of technical debt for the not-that-far-off future.
