It is difficult to believe that CF does not have a "special relationship" with YC, give PG's close ties to Project Honeypot, the precursor to Cloudflare. Nothing wrong with that.
And one could argue even the "informative and well-written" posts are always done with a purpose: recruit developers. These blog posts almost always read like a PR piece described in PG's "Submarine" essay. Again, that's fine.
But they also get promoted to the first page on HN with uncanny efficiency.
