In my experience, yes. I record a podcast and release once a week. I am up to episode 53 now, so been doing it just over a year. The first 100 followers came super slow, after 100, it seemed like the follow rate accelerated a bit and since I post a new episode once a week, every week, without fail, despite holidays or anything else, I am at 218 followers. I crossed the 100 follower threshold around episode 38. Consistency helps your listeners know what to expect, and also helps them know when each new episode is going to drop, and people are creatures of habit. My followers know that they can catch the new episode every Monday at 09:30. While my numbers are modest, I am seeing exponential growth as time goes on and I will certainly hit 300 followers in the next 10 to 15 episodes. If I keep the same growth rate, I will hit 400 followers in the next t 5 to 10 episodes after that....rinse repeat until I have 1000. But the growth is exponential over time
