I read this as: a group of professional engineers dedicated to hosting/scaling a platform designed for hosting blogs will perform better than a single random person managing a personal blog in their spare time. I generally think that's accurate.
Might just be their way of being funny, I wouldn't read too much into it. Self-deprecation is a common social cue to trigger some light, mundane empathy:
"I struggle, you struggle, (thus) we relate!"
I blame it on the spirit that being last in school is way cooler than being first, and I suspect it's as old as humanity.
