On any tech forum, there's always a lot of "why are you writing your own Hello World program instead of contributing to an existing one?" energy.

As you note, the learning process itself is worth it. I'd encourage you to keep a blog / journal for others to follow.

Most innovation doesn't involve the most qualified expert in the field taking on a project that is a sure bet. In fact, qualified experts are often too cautious to try something crazy or shake up the status quo. Back in 1991, Linus wasn't the right guy to write an operating system either, and most experts probably felt we didn't need another OS to begin with. He probably should've contributed to GNU Hurd or Minix instead.
