indeed, I like your project. Negativity of the community can be discouraging. I stopped a project of mine because of a combination of the negativity and from the reality of having to hiring and train people to use my language.
/r/programming is one of the most pedantic forum I have ever seen but I also see it as a place where programmers flee and shelter from the non-technical bullshit and vent a bit.
If you submit anything there, be prepared for harsh criticism. There is some real value in there, but encouragement and cheerings won't come from there.
My experience is that there is a lot of toxicity on the internet, but also outside of it. I'm disappointed by how toxic, money-obsessed, and ignorant many people are. On the internet, all that is concentrated and delivered straight to your face.
I would recommend presenting projects first in person to people before putting them on the internet for debate.
Imagine how it must be for the people behind Rust. Yet, people from the team regularly show up, are polite and nice and are open to arguments in spite of all the negativity they surely face. I think it is easy to become bitter, suspicious, and unfriendly when faced with social pressure, but they seem to continuously find the arguments in even not so polite comments and patiently give good insights and own arguments.
I intend to write about this, and this is a reason I am keeping some of my personal projects less open source and invite very few people in that I can mentor.
I think it is a shame that the default tends to be negative comments rather than constructive, but I also recognized that giving into toxic emotions is easy.
