I know mastodon joked about not changing their name in their recent changelog but I wish they really did change it. It’s long, doesn’t exactly roll of the tongue and it’s difficult to pronounce in most languages.
End of rant.
Edit: above all I don’t think it’s a cool name. Can’t imagine asking my friends to follow me on Mastodon. They’re just gonna think it’s something dumb or weird. At least if it had a cool name they would be curious and ask what it’s about.
The number of syllables does play a role on word length, but keep in mind that most languages have faster syllables than English, due to lighter phonotactics and lower tendency towards monosyllables. (It’s like English tries to cram too much info per syllable, and as a consequence each syllable gets a bit loooonger.) As such something like “Mastodon” might sound verbose in English, but in [for example] Spanish or Japanese it’s relatively short.
I also like the reference. It’s a critter, big, and generally associated with elephants, that are seen as sociable and smart.
(Since people are talking about your username: it reminds me some alcohol extracted from tomatoes. Ethanol, propanol → tomatol. I do agree with you that usernames aren’t good names for social networks, mine for example wouldn’t roll at all.)
