This is an image of how growing and obtaining PLN works! One of the most simple ways to develop your own PLN is through your phone. You could grow your own network via social media apps like Blogs and Vlogs software, News, Email, Reddit, etc. To be even simpler, you could just have a video chat with other people to connect and communicate.
I drew this particular image to show you what a phone could do to grow your PLN and how your PLN growth can be represented in this way (by looking at those notifications)
