Is Wikipedia actually Category 1?

Seems to require an algorithmic feed to be Category 1 - https://www.legislation.gov.uk/ukdsi/2025/9780348267174

How is "algorithmic feed" related to safety? Or is it, along with seemingly arbitrary numbers like 7 or 34 millions, a way to target a specific platform for those who are afraid to spell the name explicitly?

One of the main motivations for this law was pro-suicide and pro-anorexia content being pushed to teenage girls. In particular Molly Russell's death received a lot of press coverage and public outrage at tech companies. The coroner's report basically said Instagram killed her. https://en.m.wikipedia.org/wiki/Death_of_Molly_Russell

Of course if you get your news from HN then the motivation is actually something to do with limiting discussion of immigration or being dystopian just because.

But yes, if they could just name Instagram and TikTok they probably would.

Is search results 'an algorithmic feed'.

The phrase they actually use is "content recommender system". The definition is in the link; you could maybe see some search features falling into it but I don't see how Wikipedia as it exists now is Category 1.

Their homepage certainly is.

The homepage is manually edited isn't it?

There have been no edits for the last 6 days; then 18 days prior to that. I don't think so.

You're correct that the wikicode on the main page only gets touched rarely. It is mostly transcluding templates, which do get altered more regularly!
