I used that code with a couple tweaks. I tag !flashlight@lemmy.world in the posts so they appear there as well.

I’ve been using a similar solution with my static site at https://zakreviews.com/ for years.

You can write software to filter on arbitrary criteria with ActivityPub, or email, or IRC, or virtually any other protocol. My point is that ATProto is designed to actively encourage it, and the flagship implementation does so. Subtle hints in interfaces have a big impact on how people, including developers use software.

When a substantial fraction of users are actually using an appview with that trait, that will be great.

It’s a difference in vision, but I don’t like BlueSky’s vision here.

Combining the Reddit-like and Twitter-like experiences in one place is a little awkward, but following a blog or a Youtube-like from a Twitter-like isn’t. Having the option to switch to a more optimal appview is great, but realistically a lot more people would follow a blog from BlueSky than would use their BlueSky identity to sign into WhiteWind.

It is likely most other software will be able to consume them.

This highlights what I believe to be a poor choice in the design of BlueSky’s AT Protocol; ActivityPub software is usually liberal in what it accepts and displays, while ATProto enforces schemas (“lexicon”).

Not Lemmy, unless the post tags a community.

This is typical of forum software. Some have access controls, but they’re at the admin/moderator level.

Be the change you want to see

On my flashlight review website, every article links to a corresponding post on !flashlight@lemmy.world and displays comments from there.

Not much links to it. It’s really rare that I see a blog, social media, or non-fediverse forum post link to a Lemmy post. That sort of thing still matters quite a bit to search engines.

And that is what I would recommend against, even on a server that does not ban that age. If someone’s (young) age is relevant to a discussion they wish to participate in, I would suggest a throwaway account.

How were they revealed?

Why do you care?

If it’s just about following the rules as a matter of principle, I suggest not doing that. Nobody is checking, and saying your exact age on public social media is oversharing anyway.

If it’s about content moderation being strict enough to satisfy some comfort level, I wouldn’t rely on that, but I also think 13 is old enough to start learning there are shitty people online and how to deal with them, preferably with some adult support.

It’s interesting the number of comments about parenting advice as opposed to technology suggestion.

Was this unexpected? It has been my experience online that people are more likely to tell you what they think you need to hear than what you asked for.

There’s a hardware device with a companion app that can do charge limiting for any Android or iOS device if you’re so inclined. I haven’t used it; I use ACCA.

They’re all essentially adults now, so we don’t enforce it anymore, but they sometimes still do it anyway.

I know adults old enough they didn’t grow up with smartphones who exclude devices from their bedrooms by choice to have a healthier relationship with technology.

I don’t know you, your daughters, or their friends so I can’t make specific recommendations. What I can say is that it’s really common for teenagers who are sheltered from the dangers of the world to make more and bigger mistakes once they’re unsupervised than those who get a gradual introduction.

The two main dangers of social media for most people are:

1. Encountering assholes. For girls and women, there’s a high probability assholes will try to sexually exploit them. Since there are minimal consequences most of the time for sending “show me your tits”, they’re going to encounter that behavior eventually, and it may be easier to deal with for the first time when they have parental support.
2. Algorithmic rabbit holes. These can create the perception that problematic attitudes and behaviors are common and widely accepted when they are not. Having an open dialog with parents about anything from eating laundry detergent to Jordan Peterson can be a strong stabilizing influence.

I don’t think a closed Fediverse server is likely to serve as a first step in a gentle introduction because it has neither danger and presumably no strangers to talk to. The full Fediverse might work better, as it does offer interaction with strangers. Encounters with assholes will be less frequent than on corporate social media, and any rabbit holes will be much more self-directed.

That said, when one of them is likely within a year or two of leaving home or at least having full control of her digital life, if she wants to use some corporate social media, she’s probably better off doing that with some parental supervision and support than jumping in completely unprepared when you’re no longer in a position to prevent it.

Her friend group has a group text and she wants to keep up with everyone but doesn’t want to get the ding notifications constantly.

This seems like a good opportunity to learn how the notification settings on her phone work.

They probably will once it’s not in early alpha as the readme says it is.

If you’re hosting it yourself, ActivityPub is a separate component. If someone else is hosting it for you, they will have to add support.

There’s a significant distinction between servers that are actively malicious as you’re describing and servers that aren’t fully compatible with certain features, or that are simply buggy.

Lemmy, for example modifies posts federated from other platforms to fit its format constraints. One of them is that a post from Mastodon with multiple images attached will only show one image on Lemmy. Mastodon does it too: inline images from a Lemmy post don’t show on vanilla Mastodon.

I’ll note that Lemmy’s version numbers all start with 0. So do Piixelfed’s. That implies the software is unfinished and unstable.
