It seems relevant to HN's discussion of the story, because his blog post about leaving Google for Grab got 311 points + 182 comments https://news.ycombinator.com/item?id=16220666 , and a mainstream media article about that blog post got another 180 points + 89 comments https://news.ycombinator.com/item?id=16226439 . (It looks like you commented on both threads.)

I don't read the comment above is a reflection of Steve Yegge's importance in general, just as a useful piece of information linking this news to something HN previously thought was important (his move to Grab).
