Welcome to in-b4.com, a simple React app that allows you to enter a message and hide it for a set amount of time. Once that time passes, the message will be revealed and visible to everyone. It's essentially an implementation of the "inb4" internetism.
For example, if I made a forum post stating "Star Trek is the best sci-fi series ever made", I could create and append this link, which I set to reveal the message after a few hours:
https://in-b4.com/233655257752666628
Once the message is revealed you'll be able to see who responded as you predicted.
I created this site so I could learn about some technologies and tools I had not used before. If you'd like to know more about this project (or me), see this post about the process: https://edaemon.net/posts/in-b4
