The reason Mastodon names are like email addresses is because email addresses "won" over a lot of other options that I won't mention here because most people have never heard of them.

Why did email addresses win? Because they match how we think of community, at a deep cognitive and arguably biological level.

Need evidence? "Jesus of Nazareth" is basically an email address and, now, a Mastodon account name.

@blaine traveling churchy/merchant people had Dude von Placename type names; peasants were more like Dude the Miller or Dude the Jerk 😂
@migurski 😂 and somehow ... 😂 this place is not different. 😂
@blaine my Mastodon server marks me as Mike the Normie
@migurski @blaine sadkjksadjhkjsd
@darius @migurski you are way too famous on the internet, so I can't even find out what "Migurski" means in Polish. Clearly you need your own instance, so you can be "Mike, of Migurski fame"

@blaine @darius I think it means something like “of the mountain?” (Or hill)

tbh I haven’t dug too far to learn more. My mom’s side is an ultra-common Polish last name.

@migurski @darius heh, my mom's side also means roughly "of the mountain" (and I'm not falling for your trickery here! You'll never access my United account!)
@blaine @migurski my name means "I am a patrilineal descendant of [maybe just followers of] the seventh Imam Musa ibn Ja'far al-Kazim"
@darius @migurski I sincerely hope that in 1125 years, there are people with the last name "Frencampi."
@blaine @darius “Elon von Birdsite” 
@migurski @blaine @darius once he's broke he'll be Elon the Birdfucker.
@migurski @darius @gnat @blaine but did he fuck the bird or did the bird fuck him?

@migurski @marcprecipice @gnat y'all's Thanksgiving traditions are weird.
@nelson @migurski @marcprecipice @gnat They're practicing, they've still got a couple weeks to go.
@darius @gnat @migurski @blaine lol at the peacock watermark.
@marcprecipice @darius @migurski @blaine In honour of the change in leadership, perhaps the new Twitter logo bird should be a peacock?
@gnat @marcprecipice @darius @migurski I bet if we send this to the marketing department right now, they'll have it up by bedtime.
@migurski @gnat @blaine @darius the bird emerged, fully-formed, from Zeus’ brain…
@gnat @migurski @marcprecipice @blaine @darius in this case wouldn’t it be the bird emerged, fully deformed, from Elon’s a..?
