9k+ testers in less than 24 hours! and now what?

Two days ago, Sunday, I decided to challenge my POC website by sharing it on Hacker News to get the first feedback. I am very proud that I could make a tiny shake in the community who reacted amazingly by writing comments, voting up, sending me Emails and messages via LinkedIn. I got 9k+ testers in less than 24 hours. It was nice to see people blow my Google cloud credit up. Big thanks for everyone who gave it a try. Memorize Terminal Commands is my Sunday's project. Each Sunday, I am going to release a better version.
Now what? I have no idea what is my business goals or even how to set them. My ultimate goal is to deliver an end-2-end project. I consider that as investing in myself to improve my skills. However, I think business skills are also important if I want to move forward in my current career or even find my own way! I am very interested in hearing your suggestions and opinions.
