Use my public feeds to get the content I used to repost in X.
With customisable feeds and lists how much reposting is needed?

It’s a different era when you can create your algo and feed experience (mutes, filtering, inversions).

Your profile has a RSS-feed and can be bridged to Fediverse (e.g. Mastodon).

Hi, I am starting the process of closing the blueskyfeeds.com feed service in early July. I am having difficulty dealing with site outages, issues with the firehose, ballooning cloud operating costs, and blocking users trying to 'stress test' with feeds that store every post (you know who you are).

After a court order by the Turkish government, Bluesky made accounts unavailable for Bluesky users in Turkey this week.

I take a closer look at geographic-based moderation works on Bluesky and atproto, how it can be sidestepped, and much more

In effect Bluesky will be indirectly deciding who gets to be verified, for a large part of the ATProto app user base. Bluesky's selection of trusted verifiers may then be a locus of controversy with possible calls for Bluesky to have a formal policy (like Mozilla's) re who gets to be a verifier 3/

aint that the rub. "We want a chronological app with no ads just photos!".
"OK, here you go"
"It's a bit boring".
I'm not sure what the middle ground is, but I like the ethos behind Foto and hoping they find their feet.

Bsky's DAU as measured on the firehose is currently 2.4M

This measures only active users who like/post/follow someone. Paul's number includes people who log into the app/site but do not otherwise engage.

So ~40% of active users do not like/post/follow

Meta’s feed content is just filling the space between ads
Meta’s army of AI-powered “users” includes this “fiercely loyal mom” who bills herself as the “realest source for life’s ups and downs.”

The account was created in Sept. 2023, and has more than 1,300 followers (although how many may be fellow bots, who knows?).

Ed Conway goes looking for materials we have run out of—and retires the series after one post, because he can't find any.

Whom to trust?

Trust is relative

It takes time to build your established online identity where others are socially verifying you by associating with you with engagement, linking and referrals.

If you haven’t done that, there’s not much any third party can do cost-effectively.

The Internet: WIP
My third post ever on this site said treating people as if they are domain names doesn't pass for verification. Did anyone listen? No. Did a grift turn up? Yes.

as of this week, when you verify your account by updating your username from a default like emily.bsky.social to your website @emilyliu.me, your former bsky.social username is reserved for you automatically (and prevents impersonators from claiming it). you can revert back to it at anytime
