Finding Your Niche: Becoming an Expert in a Stack Overflow Tag

I was a generalist, answering questions on Python, JavaScript, and whatever else came my way. My reputation grew slowly. Then I found my niche: a specific, somewhat unpopular Python library I used at work. I started answering every question I could about it. Within months, I became one of the top answerers in that tag. The reputation flowed in, but more importantly, I became a known expert in that tiny community. People would tag me in questions. It opened up consulting opportunities and speaking engagements. Focusing your energy on a niche on Stack Overflow can turn you from a general helper into a recognized authority.
