Hi.
This strikes me as something of an argument for NOT posting on Steemit? I have the same thing as you on YouTube with my Wordpress blog - my hit rate and thus my advertising revenue keeps going up and up because of posts I wrote months or years ago.
Given that, why should I post on Steemit knowing that I will only get rewarded in the first 7 days? There is no comparable incentive, hence why I have a different posting strategy here to over on sites where I get a slow-burn reward, which certainly has its advantages....not least for my mental health.
