WE WERE WRONG, WE NEED A DATABASE

Summary from the TLDR Web Dev newsletter

This author built a web game called "Binary Duel" using only Go and claimed that features like a cache, queue, and database weren't necessary. However, he admitted that his initial claim was premature and wrong. For better user retention, he decided to add features like a database, login, leaderboard, and ranking system, using Go to implement solutions like in-memory caching and bulk database writes efficiently.
