It’s true that random professional posts are the best part of HN but I mostly care about the posts that appear in /best for things outside my interests.
Karma points enable this convergence because they are the only metric that we can do data analysis on comment quality, and so build into the various user interfaces.
So we can all think of many combinations of karma and account - 4chan, reddit, hackernews, youtube (which was trying to require given names); The concept of a website displaying account progeny is both an affront to privacy (in both directions) and a remarkable way to improve comment quality, which I make no effort to define.
The invitation only model seems to scale only so far, as all "cool parties" start off cool because only the cool people are invited (cool in this sense means compatible: consider both artificial and natural boundaries such as a physical party of people congregating for social purposes, a private web forum, or even the internet itself, which was initially available to only those that could enter and navigate it). We have euphemisms such as "Eternal September" to connote the perpetual ruining by outsiders infiltrating what was previously more private.
I vastly prefer to allow the unsanitized comments to enter a feed, and root through them so that people are not behaving as though being watched. It's exhausting but because both extremes are allowed to exist, the comments with the highest signal to noise ratio are often the most honest. Anecdotally I have found (exceedingly rarely) the most honest, insightful, or inclusive comments are on a site like 4chan, with the least restrictions and the least incentive to build a reputation (it's impossible). On hackernews, and I know I am projecting, I believe that we artificially act better than we are, on average, because we have something here to lose. A clever post turns into a job reference, or a reference to work becomes discovered by a future boss, etc.
Ultimately I am glad that all of these combinations exist. Losing a cultivated registry of who's who would have an immediate loss of largely high quality comments, but losing the wild west of anonymous bilge leaves us with no place to be our most honest, regardless of how much or how little it contributes.
Have a site with one public user account that is linked to a reputation and a shadow one created simultanously for snark / sharp riposte's / unpopular opinions.
Most of the time when I see unproductive conversations go back-and-forth here, it's often clear (or I'm quick to give the benefit of doubt) that at least one of them is a newbie trying to meaningfully contribute to a conversation where they don't know how much they don't know. But there's a sizable number of posts where I'm convinced the poster is a passive aggressive asshole that knows exactly the game they're playing. As long as they can hold a conversation with the surface level appearance of someone acting reasonable and polite, they get to be wildly disingenuous and/or cut people down nastier than the kind of comments that would be immediately moderated away.
I've had my projects (see my hn profile) or my blog posts hit lobsters a bunch of times and finding myself unable to respond to the comments as I don't have an account there.
Invite only tech communities can actually be harmful if these open access communities don't also exist. Closed communities end up reinforce existing inequalities and in-group biases. If it were as large and influential as HN, inequality like this would be a real issue.
Indeed sometimes the most insightful comments here come from one time use anonymous/throwaway accounts.
There's plenty of reasons for throwaways besides just being 'nefarious'.
This is now a myth. HN used to be like this but look for yourself, it's no longer like this. It's no longer worth my time to dig for worthwhile nuggets in the HN comments nor is it worth my time to post a high quality comment because I know the only responses will be nitpicks and a few worthless internet points.
PS: There's a vague rule about not criticizing HN that gets invoked fairly often. Be prepared for this thread to be gassed.
EDIT: Dropped off the internet due to a DOS? Snort is fun. Hi dang and friends!
It doesn’t happen often, but HN doesn’t often discuss things outside of its wheelhouse either. Usually we’re litigating matters of opinion, usually about whether JavaScript is bad or not.
As for comments by people with domain knowledge, I was just looking at this a couple weeks ago. Here are a few I randomly ran across:

There are tons of these, many of which don't get much notice. We've periodically published a highlights list, but I'd like to come up with a way for users to nominate such posts as highlights when they run across them... something like a positive 'flag'.
I think Lobsters has done extraordinarily well in attracting domain experts while keeping out the valley-style surveillance capitalist blockchain AI expert “investors”. Non-tech articles are explicitly off-topic on Lobsters.
Lobsters may have fewer experts in total numbers, but experts make up a bigger share of the community, which means that the amount of pointless, fluff, snarky comments is way lower.
The hats¹ also means that experts are easily recognizable, because they can display the badge when they comment somewhere as an expert-on-that-topic.
