I don’t have a good idea as to how many people listen to your posts.
Are you emphasizing on audio now?
First, most of the posts on my website are in text form. It was just recently that I started Clubhouse meetings for our LinkedIn group and I have recorded them and put them into posts on my website. So most of the people would read my posts and not listen to them.
Second: I have an audience of about 250,000 people on social media (LinkedIn and Facebook), and I am in regular contact with about 16,000 people via email. I do not think that these are important numbers because I am addressing "breakthrough innovation" people and not "incremental innovation" people. It is very clear to me that this is only one or two of 100 people that work in the area of innovation.
