As a WordPress expert, I subscribe to RSS feed with Feedly app. I can read it online, on my MAC or iPad. I may have 10 differents feeds but not more because it will be too much to keep up. I find it the best way to keep up with my peers and industry. I subscribe to different kinds of information like security, design, themes, plugins... etc. Also, as an entrepreneur, I have few feeds as well about it. I like short video and Udemy is good for that.
