What are your niches?
I'm always interested in the niches people focus on when buying domains. As a hobbyist, I pretty much focus on one word generic domains with very broad appeal, or the occasional high quality 4l pronounceable. I also stick firmly to .com, org and io.
I'm always intrigued by those that are willing to be more precise with their intended buyers, and often watch in amazement as domains I wouldn't dare touch sell for significant sums.
So, what are your niches? Do you have any specific industries…
