Ask HN: Should I keep investing on my blog or should I focus on something else

Hi all. I'm trying to boostrap a Substack site but I'm not sure if I should keep investing effort on it.

I'm asking the community to be brutally honest and let me know if you find quality on the content I've been posting there or if should I just give up and focus my energy on something else.

Thank you for your time, Alexandre Gomes
