Viss@anildash arj. from the 90s. because nobody remembers the compression wars :D

kcǃ@anildash I’m going to go with JPEG. A dependable workhorse. Can get a bit messy at times, but is also capable of so much beauty and function.
@anildash hmm, I think I should’ve gone with mp3. But I guess JPG was what I thought of first so there’s that 🤣
Great question!
James Bartlett 
@exkclamation @anildash They're both the same concept applied to different things. I've even heard mp3 described as "jpeg for audio."
@JamesDBartlett3 @anildash I love that! I guess if nothing else I am consistent 🤣
Gus Mueller@anildash .sqlite

Ryan Randall@anildash Does "those tiny zines you'd occasionally get included with a cassette tape" count as a file format here?
Thinking specifically of the little booklet with Public Enemy's Fear of a Black Planet tape, which totally blew my preteen mind.

keeps vis.social runningcsv
because I work with data, and I can write a script to convert it into anything...let alone pull it into a viz, which is when I fly.
Leon Bambrick@kristinHenry @anildash Kristin I can’t believe how many other file types I had to wade past until I found you here, giving the only *correct* answer.
I don’t share this link with just anyone - my list of favorite csv things: https://github.com/secretGeek/AwesomeCSV
dynamicMy sentiments exactly, @secretgeek. Not sure why I had to do so much scrolling to get to .csv.
.csv is definitely my choice.
Eric A. Meyer@anildash Text, because it’s the basis of so many formats. UTF-8, if I have to pick a specific text type.
