The question seems to imply that this ratio is problematic, but it is in fact fine.
There this sense now that “being a creator” has intrinsic value, but this value is an artifact of platforms that exploit its users creations. So much so that we now have an immense amount of low quality fast food grade, in fact toxic, content. Content pollution.
So, whatever the ratio is. If you want to post post, if you want to comment comment, if you want to lurk lurk.
As long as we are all enjoying the experience, who cares?
Right. It needs to work well for people who like posting and commenting.
