I think it's well-known fact everyone should start doing content marketing from DAY 1 of their product.
I believe anyone should start creating content even before the MVP.
Most founders only create a basic landing page and think it's enough.
The fact is it's not enough. The general audience/users do not get the full picture of your product just from a fancy landing page. They need to read your story, why are you building it, how it can be helpful to them etc.
Once you have a /blog on your domain, you are already ahead of most of your competition.
I am building software for the last 8~9 years. Still, I feel lazy to set up a WordPress site.
I love writing in Google Docs and most people love writing in GDocs.
That's why I started building https://docswrite.com (Create a blog
from Google Docs in 30 seconds)
It makes blogging easy for anyone. You can connect your custom domain or configure it as a subroute (/blog)
