When I started browserless.io, I was having a heck of a time getting Chrome running properly in Docker. After about 1 month of hit-n-miss `docker build`'s (which was taking ~15 minutes each time due to the amount of deps and lack of layer caching therein), I decided to sort popular open-source libs by comments and reactions. To my surprise I wasn't the only one experiencing this issue!

This actually turned out to help in two ways: I knew _exactly_ what to build, and where to find first users. After that I point I really haven't had to market or even cold-call anyone since (thanks to SEO and GitHub) most folks find the solution when there in the midst of the problem.

If you're looking to build something, and are tech-savy, I think it's an interesting thing to go to popular OS projects and do some research. It'll open your eyes as to what others are needing and (sometimes willing) to pay for.
