I've had it happen numerous times that maintainers aren't interested in critique or elaborate suggestions; one has to move on before getting too invested/angry. Having your own work being "improved" by someone else can feel like a personal attack, and I'm not sure how well I'd handle that myself.

However, I've also encountered the opposite, maintainers who are very open to anyone who offers concrete improvements (even small ones), a real winning mentality.

@Rahtgaz we thank you for your input but it sounds like you don't have any experience with computers or programming.
Oh, I bet that rustled your jimmies!
