This platform has no limits for the medium in which messages are communicated. I feel as time and development progress, media preferences (video, podcast, writing) can be user preferences. That way, people can author in their preferred form, and people can consume in their preferred form. And for some, it would be all (written from for at home, audio for work/commute, video for lunch breaks, etc.)
I agree. There are no limits, let everyone shine with what they can do best :)
