The new followers are trickling in at the moment for all accounts but, that'll change and perhaps already changing. I have noticed a few new account follows and votes coming from new Steemit signups with 15SP as price has increased. When the bull run comes, there will be many more onboarding and even though they won't have much value, some of them (like Asher has shown) will find support and do well over time and strengthen the ecosystem further.
