The most useful online community I can think of is definitely LinkedIn. Especially, if you are interested in understanding a particular business sphere, I believe LinkedIn is the best place to begin your journey.
The first time I started using it was right after I started studying PR and Advertising. I was really interested in the constant movement of the industry but I didn’t know how to follow every trend and keep up to date, which is very important for PR.
So, after I followed a few basic profiles in LinkedIn, many more started to appear as proposals and I would say that now my interest has been fully satisfied. What is more, after I found out interesting and important people for the industry I followed them on other platforms or discovered their websites, which enriched my industry culture even more.
I believe that LinkedIn remains the classiest platform providing valuable and trustworthy information. It differs from other platform because it is serious and grown-up platform, which is not interesting for young teenagers to post their thoughts or pictures. If you don’t have a profile at LinkedIn yet, it is about time you get In. https://gb.linkedin.com/
