Wow, congrats! 600 articles is crazy cool!
I've started writing to Medium this year and just hit 100th article yesterday.
I agree with you it is important to write consistently.
My simple recipe has been:
- Publish daily
- Use popular publications
- Read popular stories
Doing this I've seen linear growth in views with some HUGE spikes: Last month I wrote a piece that got 36k views, which was more than all of my other stories combined... I wish I knew how to do it every time ;)
