AC/DC vuelve a tocar en Chile en 2026. Imposible no acordarse de ese épico concierto en el Velódromo del Nacional, allá por octubre de 1996, cuando con @tengochicle.bsky.social saltamos un metro al sonido de Back in Black. Mejor concierto de rock ever.

Great opportunity for fielding a pre-post study on the spread of junk content on Meta platforms... oh, wait. We don't need such study. We know what will happen. Just look at Elon's X.

Awesome design, yes. Important findings, too. Just impressed that not a single article from communication sciences is cited. Whole theories in comm, most notably cultivation, predict a causal-effect relationship between crime TV shows and crime attitudes and behavior. #academicsilos
