I found it very interesting that even accounts with 0 SP have a little bit of recourse credits.
This makes Steem the only freemium blockchain in the world (that I know)! It also explains why accounts have a little cost to create them. Free accounts + free transactions = spam (bloat of the blockchain).
I record these videos in my garden. I just talk freely about Steem in one recording with a general subject in mind. Sometimes I lose my train of thought and then I start the whole video over.
I trained myself to do it in one sitting, I'm not a fan of jumpcuts + if I can't talk about something normally for ten minutes I don't understand the one thing I'm talking about. At least that's how I see it.
I always add the text later. Sometimes I don't even know where the vlog goes while I'm making them.
Seems like a very efficient system - your video ideas feed the text content and you are expanding your reach while presenting them on both text and video.
