The bang (!) version originated from Laconica later renamed to StatusNet and later became GNUsocial. It was the very first and original Fediverse software, way back in 2008. It was always meant for groups.
Mastodon® software is planning on adding groups too, and they probably will use bang (!) as well. Besides, it's the only logical reason.
The sharp/pound/hashtag (#) is for hashtags ever since hashtags were invented. While the atsam (@) is for user accounts that has been around since the 90s (afaik).
What looks like an "email" is called WebFinger. It is actually a webstandard (see: https://en.m.wikipedia.org/wiki/WebFinger ). Aside from email addresses and OpenID, the first social network [software] that used it was Laconica/StatusNet/GNUsocial in 2008 (the birth of the Fediverse).
Since Threadiverse software like Lemmy, Kbin, and Mbin were built for the Fediverse network, they're following the standards and established practices, instead of reinventing the wheel. If they were joining the Matrix network, they no doubt would follow the standards and practices in the Matrix network.
That's the answer to "why".
I miss a lot of folks from the #identica, #statusnet, and #pumpio eras of the #fediverse. I still follow se but they're lost in the sea of other posts or they are in different timezones so I don't catch them. Other folks I've lost entirely and only have pleasant fleeting memories about them.
How do you know when you're in the good times?
Gnihihi, in alten Dateien gewühlt, eigentlich was ganz anderes gesucht...
Das gefunden... 6.September 2014 #statusnet #quitter #gnusocial #fediverse
Liebe Twitterer,
unser Ansturm auf Quitter(https://quitter.se) hat offenbar den Server ( http://old.quitter.se) arg belastet.
Dadurch wird die Seite langsam, was schon viele von euch bemängelt haben. Es lässt sich jedoch ganz einfach vermeiden.
Wie ich an mir selbst festgestellt habe, ist die ganze Sache nicht so ohne Weiteres für jeden verständlich...
Der Server, also old.quitter.se ist einer von vielen im StatusNet. Eine Liste möglicher Server im Statusnet findet ihr hier:
http://www.skilledtests.com/wiki/List_of_Independent_Statusnet_Instances
...
Ihr könnt euch bei jedem x-beliebigen dieser Server einen Account anmelden. Es muss nicht zwingend old.quitter.se sein. Nehmt bitte einen anderen!!
.... Also, seid bitte so nett, und richtet euch eure Accounts nicht alle bei quitter.se ein, nutzt auch die vielen
anderen! Ansonsten vergeht uns auf Quitter bald allen der Spaß

Does anyone happen to know whether the old data of #identica users that weren't migrated over when it switched from #StatusNet to #pumpio has been archived anywhere? I see a mention that there was a plan to upload it to @internetarchive, but can't find anything more than that. #fediverse #ostatus
From @tonytins on the history of the Fediverse, Mastodon, and ActivityPub, and how it has similarities to Bluesky's history.

each independent instance can select which other platforms to federate with (similar to now?).
@Gegenwind @ErikUden vorallem weil ja #StatusNet als vorgängerin von #ActivityPub bereits funktionierende !gruppen hatte [wurden mit ! statt # adressiert und konnten erstellt, abonniert und moderiert werden]
Fediversum var länge ett tillhåll för minoriteter och nördar. I begynnelsen fanns OStatus som en standard för federerade kommunikationsnätverk. Det var ett sätt att beskriva hur en räcka öppna protokoll som Atom, Activity Streams, WebSub, Salmon och WebFinger kunde användas för att olika sajter skulle kunna utbyta meddelanden.

#StatusNet integrated a lot of things into itself when it was new - URL shorts, maps, feeds...all of that is of no use these days because it's gone or is weaponized.
I still have some StatusNet instances under my control, so I decided to see what could be removed from the main page to harden the interface a bit.
Turns out, quite a lot!

#StatusNet is the granddaddy of the self-hosted twitter-likes. While it's long since passed into legend, there are still a few instances out there run by private parties.
I have a couple under my wings, er, hooves, and some time ago I set about making them a little more useful to me. For example, sending emails on posting and cleaning up some of the non-functional cruft.

In many countries you can now link Threads with le fédi. To an extent you can do the same with Bluesky.

Jag skrev tidigare om att det är nödvändigt att testa en massa saker för att kunna skriva ordentligt om Fediversum. Dessutom. Att skriva om Fediversum innebär att läsa en massa.
