The original title is "How to start a niche content site", which IMHO accurately reflects the contents of the blog post.

I don't see the word "hobby" anywhere on the page.

He uses interests instead. "This is my unconventional advice: Start with your interests." To be fair he doesn't say to use your favourite hobby either - he says use the best combination of your interest in it, how niche it is and how good it is for easy high volume search keywords. Which seems like a reasonable enough criteria for a topic you can make a spammy content farm about.

Understood, and the focus appears to be very much on the creation of a content site and its monetization, rather than the hobby/interest bit.

I don't think that's inherently bad, but the (now updated - thanks whoever did that) title better reflects the content IMHO.

(For me at least, the original title was a bit click-baity too).
