Love the 50 case studies on the site. IndieHackers who don't know how to market their product can start reading & perform practical tips for their website.
As there are 50 case studies, most of them will overlap with your product anyways. I have really enjoyed some case studies.
I have been reading ZTM from day 1 and have been impressed by the quality of the insights and consistency with which Andrea delivers them. Great read if you are interested in receiving actionable advice on how to grow your startup!
