Building a website where users can have profiles and message each other is doable. In my opinion, Omegle.fm Text Chat - Your New Omegle Alternative for Random Chats! could be a good starting point for inspiration. You’ll need to use web development tools like HTML, CSS, and JavaScript, along with a backend language like Python or PHP. You’ll also need a database to store user profiles and messages. As for best practices, make sure to prioritize security, privacy, and user experience. Test your site thoroughly and gather feedback from users to make improvements.
