Thanks, this is very interesting. Mind if I ask how you determine relatedness? https://anvaka.github.io/sayit/?query=UsbCHardware This subreddit is very small, I am a very active poster there and yet I recognize none of the related ones.
Unrelated, but had to say it somewhere in this discussion: Thanks @anvaka for your open source graph libs! Way more performant than anything else I've tried.
