Some people learn also by sharing their current thoughts and learning from how other people react. One way to gain perspective about your ideas is to communicate them.

I have no idea about the reasons why that Googler published a blog, maybe he's just self-obsessed idiot who doesn't give 3 fucks about other people's perspective, like one would think reading the reactions here.

But I don't see an issue in putting out random thoughts on a small personal blog with a comment section.
