Four stars. It's a decent collection, definitely a good starting point for anyone wanting to explore ChatGPT's capabilities. I found a lot of useful prompts in there that sparked some really interesting conversations. However, a fair number felt repetitive or too similar to others, and some were just plain underwhelming. It could benefit from better organization and perhaps some categorization to make finding specific prompts easier. Overall, it's worth the price for the sheer volume of prompts, but don't expect every single one to be a gem.
