What was your first language and what did you make with it?
Me... I learned some rudimentary HTML & CSS on Neopets and made a fan site for MTV TRL veejay Jesse Camp, who was my celeb crush at the time. (Bonus points for anyone old enough to remember him.) I think that counts, right?
Me: KhanAcademy... Because I thought it was so cool... Then I gave up until making a CYOA (choose your own adventure). Something around those lines. Then my friends introduced me to repl.
