There's a difference between saying I'm going to do something that has already been done but I'm going to roll my own compared to look at this cool thing I've done that nobody else has done. There are plenty of bits of code that I've written that easily could have been handled by something along the lines of a 'npm install' but then I wouldn't have learned anything, but I never released a Show HN or written a blog to toot my own horn for reinventing the wheel and acting like it was the first time a wheel had been used. But as far as being alien to me, any time someone pats themself on the back with public posts about anything is alien to me. I'm fully aware that if I could think of it, someone else out there has already done it. The number of times I've done an search for something I'm working on that hasn't had a post of someone else doing it approaches zero.
