On more than one occasion, after having told a client to SHARE the premiere of their radio show on their personal Facebook page... the client balked; literally leaning back in their chair with an unconscious swinging of their head right and left; it was baffling. Why would you NOT want to share this new chapter in your life. Your family and friends are usually the most supportive.
So, instead, I directed them that they HAD TO make a Facebook page or separate account (Twitter/Instagram), just to market their show. I always recommend professional accounts for every type of business. Even if the business is just you. Being on social media today is an imperative... you have to go where the people are. With everyone online, including the old formats of communication (radio, television, newspapers), the people are on the web and the web is rife with social media choices.
I'm a huge proponent of using what you already have. If you love twitter, make a new Twitter account. If photos and Instagram is your thing, make another Instagram account. If you can't stay off Facebook, make a professional Facebook page. Separate, but manageable. You Twitter phone app and Instagram allow for easy switching between multiple accounts and Facebook pages can be managed from your personal account.
I cannot recommend a professional page enough!! Convert your Instagram to a business account. Make a PAGE rather than a profile on Facebook. Business pages are free and they give you insights. They give you demographics. They give you numbers. They can help you reach more people. Make a Google Plus page, because everyone uses Google to search. If you have a brick and mortar, claim your listing on Yelp and monitor what is being said. Set up Google alerts (or Yahoo alerts) for keywords in your industry or even, just for your name.
Get professional. I can help.
