I can use Instagram on my PC, but I can’t post from it. But no need now that I have the phone. How do you use the business aspects of Facebook without a personal account? Did you know there is a publication on Medium devoted just to social media? It’s called Germinate. If you write posts specifically about social media marketing, you might consider applying to write for them. It might be a good fit. Posts published by Medium publications often get more views than those you publish here independently.
