It’s popular now to craft podcasts, because people don’t watch talking-head videos any more. Nothing against those: videos have their place, especially for showing, but podcasts are better company when you’re on the go.
However, I myself am fond of online text. Text is fast, informative, inexpensive and easy if you pay attention to usability: headlines for skimming, the main ideas first, casual language, and a chatty tone.
Communicating online through means like Twitter, Facebook, chat, and even FAQs, can improve the impact of your writing. The interactive element helps us produce useful content, answer the right questions and use the same language as readers.
As Jussi Pullinen put it, “Now, when everyone and his cousin has been making videos” and podcasts, it’s worth considering whether text might after all be a better option.
