General community for news/discussion in the UK.
Less serious posts should go in !casualuk@feddit.uk or !andfinally@feddit.uk
More serious politics should go in !uk_politics@feddit.uk.
Try not to spam the same link to multiple feddit.uk communities.
Pick the most appropriate, and put it there.
Posts should be related to UK-centric news, and should be either a link to a reputable source, or a text post on this community.
Opinion pieces are also allowed, provided they are not misleading/misrepresented/drivel, and have proper sources.
If you think "reputable news source" needs some definition, by all means start a meta thread.
Posts should be manually submitted, not by bot. Link titles should not be editorialised.
Disappointing comments will generally be left to fester in ratio, outright horrible comments will be removed.
Message the mods if you feel something really should be removed, or if a user seems to have a pattern of awful comments.

Do you ever sort posts by "hot", "active" or even "top 6 hours"? They're all algorithms that predict what you're interested in. Less complex than something like YouTube or Instagram, but the same core principle.
The amount of content published on the internet each day makes some kind of sorting necessary. Browsing YouTube by "new" would be a cluttered mess, even with fairly narrow categories. Over 11,000 hours of new video are posted every hour - we need some way to automatically sort the wheat from the chaff, and that means some sort of algorithm.
So how do we build an algorithm that delivers what we want, without giving people too much of what they want if they want something potentially harmful? As far as I know, nobody has found a good answer to that.
Well I mean obviously I'm not against algorithms in general. They're just mathematical functions to achieve a goal. Each HTTP request generally uses both encryption and compression algorithms and that's highly useful.
I'm questioning the usefulness of profiling and targeting users with specific content. The Lemmy algorithm isn't that complex, it doesn't build a user profile on you, it just goes by general user engagement. That's fine. Further by virtue of it being open source, Lemmy wouldn't have a "black box", it'd be open for anyone to view and analyse.
Comparing Lemmy to YouTube/Instagram/Facebook/Twitter and the like makes for a rather poor comparison.
Lemmy's simpler algorithm still has the same the problem though. That's been seen time and time again on Reddit. Humans will actively curate a feed of content they find engaging and avoid content they disagree with. This leads down exactly the same rabbit holes as if you let an algorithm curate a personalised feed for that user.
