It's not just local news. Even the Washington Post's comments section is awful. Not just in terms of the content, but also the UI. For example:
https://www.washingtonpost.com/graphics/business/coronavirus...
Who wants to scroll through 1k comments in a narrow, awkwardly-paginated column? They also allow posts from anyone with an email account (mitigated somewhat by the paywall on most articles) which results in a lot of high-emotion, low-information spam. By contrast, the Wall Street Journal limits comments only to people with a subscription. Perhaps as a result, the WSJ comments section is generally of higher quality with e.g. better spelling/grammar, less flamewar, and a higher signal-to-noise ratio.
