Every profession has its gaffes but that doesn't negate the folly of deliberately ill-conceived work done by amateurs. Technically mature infrastructures crashing wouldn't negate the folly of a first-time developer trying to launch a public service with loopdy-looped cargo-culted spaghetti code on a shared host gator VPS.
Adoption is really important for social media to succeed and be useful to its users and image is really important for social media adoption, generally, even if not for you. But I guarantee its influenced your choices more than you could feasibly perceive. Would you still use HN if it used the default bootstrap layouts? Or a ton of slick graphics and heavy animations? Would enough other people be put off by it not to bother?
You can't guarantee everything will strike everyone the same way, but there are wrong answers and it's not even mostly subjective. In an alternate Twitter-free universe if someone wanted a noun/verb for a deliberately lightweight communication broadcast into the ether over the internet, I'd bank a grand on marketers agreeing that a cheerful, sharp little chirp from a nimble, energetic bird communicates that better than the plaintive sounding crescendo of a giant plodding extinct earthbound mammal which also is outdated slang for a fart.
Nobody user is out there weight the pros and cons of the post name when deciding a social network— it's all about that first visceral impression that makes people think "this is cool and exciting" or "this is dull and lame."
