I don't know what the very first thing was back when I didn't yet have internet and could only use it when visiting my uncle who did.
But I remember the first site I visited after I had internet myself. I went on the Cartoon Network site to play some of the games they had.
Heh, my first site was also Cartoon Network. And I remember the voting too, we had them in my country too. I can't recall if I ever voted myself, but I remember some of the 24 hours days. Sometimes I loved it when it was a show I liked and sometimes I would be like "Well what do I watch today now?" if I wasn't a fan.
