Open Library is one of the main data sources for Bookwyrm's book data. Bookwyrm is an application in Fediverse that can be used to find and write reviews of books. I wouldn't see that as a contradiction.
There are also a few offers for managed hosting of Friendica instances, see Hosting a Fediverse instance (a list of providers)
Everything is better ;-)
i.e. mailbox.org, posteo.de; there are also protonmail and tuta.com, but they don't have IMAP
There is already a more up-to-date version of the second graphic (including mbin and loops):
Ok, with all pictures in replies it doesn't work yet or only in the other direction:
This Lemmy thread seen from Friendica + Mastodon
Friendica shows all pictures of Lemmy, both in posts and in replies. The other way round only in OP.
This is a really good introductory video that explains the Fediverse. Very clear, good examples and for a target group with no prior knowledge. So if you want to recommend other people to join the Fediverse, this might be a good start. There are insights into Mastodon and Pixelfed in particular... but Lemmy is also a topic in the video... (Thank you @[email protected] !)
Let's hope that there are also a few organisations that run Friendica instances so that the offer becomes a bit bigger. In the last two years, everyone has been totally fixated on Mastodon and many have opened a Mastodon server without realising that there were other options.
Pinetta is under development: "A FOSS, federated, ActivityPub-enabled pinboard thingy, in the style of Pinterest.". I don't know anything else about it, but only discovered it on this list: delightful fediverse apps ("A curated list of server applications with support for the ActivityPub protocol (known as the fediverse) and related standards.")
It has successfully reached Lemmy ! 🚀
The interface design is based on how iOS works, for example to move an icon on your phone long press one of the icons and wait till they all go wiggling and then drag the icon to where you want to have it.
In case you don't like the interface, you can also simply install a different launcher and set it as the default start app. There really is a lot to choose from: https://android.izzysoft.de/applists/category/named/tools_launcher?lang=en
Yes, it still largely works, but the web front end is broken. It works via apps or alternative frontends, for example: https://alexandrite.app/feddit.de
The main admin of feddit.de travelled abroad a few months ago and has since disappeared . The other mods couldn't fix the errors because they don't have the password for the server administration.
However, many communities have already moved to feddit.org because it is not foreseeable whether feddit.de will work again.
If you select ‘Forum Discussions’ under ‘What type of content do you want to see or share?’, NodeBB, Lemmy, mbin, Piefed and Lotide are then recommended. That fits well.
But if you select ‘Social Media Post + ’Forum Discussions", Mastodon, Misskey and other microblogging services are recommended, as well as Lemmy. But not mbin, which actually offers exactly this combination, and also not Friendica, which can do micro-/macroblogging, but also offers forums/groups and federates best with both directions.
So it's perhaps a little under-complex, but nicely done and a good new contact point for interested people.
