My account here is about 1-2 months old. I have enough followers to get daily interaction. But my point is, I don't need any followers at all. I am here to find interesting news and I get those by following others. I am free to comment on posts that others have written and if what I write are good comments, I will get replies and engagement and sometimes people follow back. It's a simple and organic process that would work for anyone. If anything, we would need a directory that analyses what topics users post about and then if I am into web development, the directory can tell me the 10 most active web development npubs so I can then easily follow them all and get my timeline bootstrapped with relevant content.
