It took me many months to hit 400 followers. You're making good time, well done :-)
Actually in the same few weeks I was on Steem as you have been, I still had 0 followers.
In fairness to myself, feeds were not implemented back then ;-)
There's great charts for tracking your progress on Steemwhales.com.
Oh wow , I'm just lucky πππ hope you are getting a better following now !
