OReilly Learning Platform for Developers

I mainly use Safari online, like the OReilly learning platform. I think Twitter is very low level, low barrier of entry if you want to share something. And anytime I need something quite deep, there is a book or there is a video or even the conference are really, really advanced. So what was the platform for people who doesn't know like me, for instance? What do you mean? It's kind of nice to see like, because sometimes you don't have the time to write a nicely written article and make knowledge.
