Common advice tells you that you need to focus on creating the highest quality content possible.
I can't say I agree – at least not upfront.
When you're just starting out with content creation, what do you lack most?
How are you supposed to create ANYTHING high quality without a baseline of experience and skill?
You don't (unless you're a prodigy.)
Posting a high quantity of content in the beginning can lead to to understanding what quality actually means for your audience.
Optimizing for quality from the start is a form of perfectionism.
And perfectionists have a hard time shipping.
