I thought it was pretty interesting, and felt was inline with the spirit of the guidelines:
On-Topic: Anything that good hackers would find interesting. That includes more than hacking and startups. If you had to reduce it to a sentence, the answer might be: anything that gratifies one's intellectual curiosity.
More importantly, it's not a "toxic" subject - something that will get people riled up, like economics or politics. If you don't find it interesting, it's pretty easy to ignore, as long as there aren't too many other 'interesting tidbits' stories.
