I'm new to this breed of podcast, however am finding this one fascinating. This is a half instructional, half sociological look at professional social media that is basically podcasts for pro Instagrammers. Hashtag Authentic is hosted by Sara Tasker (with an 158k-strong IG following), who runs online courses in Instagram and has a blog, Orla and Me. One week the podcast will be collaborations with other 'grammers on their experiences in what makes an account successful, the next it's very practical advice, like why it's still important to have a mailing list. On another week, it'll be about the psyche of a social media professional — how to manage self-doubt, how to keep yourself from falling into the comparison trap, and why you need to stay true to your creative instinct.
