That's true, but the flip side is selecting heavily for public commentary from people who are already invested in—or at least generally open to—the tool in question. But, of course, that means selecting heavily against the people who see immediate, significant problems! I've run into this problem repeatedly on Goodreads where wholly mediocre works get high ratings because of aggressive selection bias. I generally like fantasy, but I've stumbled on some painful stinkers thanks to this dynamic. It's doubly reasonable to value first opinions on languages like Go since they intentionally aren't doing anything fundamentally novel. With a handful of exceptions, Go is a remix of ideas from mainstream languages that we've all seen before. It is about as far from a new paradigm for programming as you can get, and that's the point! Hell, that's the main thing people praise about the language: "I could pick Go up immediately, without needing to learn anything new"...
