Internet DNA Podcast

As a small business should I be using Facebook or Instagram, should I be using a market place like Etsy, Ebay or Not on the High Street or should I have my own website? And if I have my own website do I need a blog - can you keep a blog up to date? - and if not what to do. Then should I have eCommerce on my website if I sell products or just an enquiry form? For once all your questions are actually answered with no curve balls, just a little underwater sounds and a ticking clock (sorry!).
