Caveat: I consider these minor issues, I hope I don't come across as too accusatory.

Interesting, why's that? :)

It seems that the reason for cross-posting was that you personally found it interesting. If you use the EA forum team account, it sounds a bit like an "official" endorsement, and makes the Forum Team less neutral.

Even if you use another account name (eg "selected linkposts") that is run by the Forum Team, I think there should be some explanation how those linkposts are selected, otherwise it seems like arbitrarily privileging some stuff over other stuff.

A "LinkpostBot" account would be good if the cross-posting is automated (e.g. every ACX article who mentions Effective Altruism).

I also personally feel kinda weird getting karma for just linking to someone else's work

I think its fine to gain Karma by virtue of linkposting and being an active forum member, I will not be bothered by it and I think you should not worry about that (although i can understand that it might feel uncomfortable to you). Other people are also allowed to link-post.

Personally when I see a linkpost, I generally assume that the author here is also the original author

I think starting the title with [linkpost] fixes that issue.

I think its best to post this under your own account.

there are so many projects which continuously replicate what others have done before; projects with very similar messages, but mostly separate communities, infrastructures and identities.

Some examples would be useful.

have you seen someone that is not top 10 attendee in an EA organization?

Julia Wise, who works at CEA, studied at Bryn Mawr College.

(Another comment of yours makes me think by "top 10 attendee" you mean "has attended a top 10 university".)

the child is adding an expected value of $27,275 per year in social surplus.

It would take $133,333 per year to raise a child to adulthood for it to not be worthwhile

I think the comparison of "social surplus" to effective donations is mistaken here. A social surplus of $27,275 (in the US) does not save 5 lives, but an effective donation of that size might.

There used to be such a system: https://forum.effectivealtruism.org/posts/YhPWq784eRDr5999P/announcing-the-ea-donation-swap-system It got shut down 7 months ago (see the comments on that post).

Some (or all?) Lightspeed grants are part of SFF: https://survivalandflourishing.fund/sff-2023-h2-recommendations

One outstanding question is at what point AI capabilities are too close to loss of control. We propose to delegate this question to the AI Safety Institutes set up in the U.K., U.S., China, and other countries.

I consider it clickbait if you write "There Is a Solution", but then say that there are these AI safety institutes that will figure out the crucial details of the solution some time in the future.

edit: the issue raised in this comment has been fixed

In my opinion you have not really argued why it is neglected. As a starting point, they seem to spend roughly $35 million per year: https://projects.propublica.org/nonprofits/organizations/824506840. $14 million of those are for salaries, so I would be surprised if new features are strongly bottlenecked by money and talent.

I am just guessing on these issues, but my suspicion as for why some features such as "live location sharing" and "display past encrypted messages from the group chat you were not a member of but only just now joined" are not (yet) implemented because they do not fit well into Signal's approach to security/privacy.
