What know that before starting Facebook, Mark Zuckerberg built a number of different sites for himself and others. The most memorable was Facemash, the site that he built as a freshman that acted as a "Hot or Not" for Harvard students. But according to the good folks at Hacker News, Zuck was building web pages way before that with the help of Angelfire.
The site, which sports a banner saying "Mark's Homepage" with a subhead which reads "Hello and welcome to my page! The only site where a yellow eye blinks at you," was reportedly made in 1999. The site has six pages including an "About Me" page wherein the author introduces himself with:
Hi, my name is...Slim Shady. No, really, my name is Slim Shady. Just kidding, my name is Mark (for those of you that don't know me) and I live in a small town near the massive city of New York. I am currently 15 years old and I just finished freshman year in high school. I have remodeled this website in an attempt that perhaps some search engine will recognize it. I am trying to promote my new AOL Program, The Vader Fader, which you can download elsewhere on this site. It is a decent fader. If you have any comments about this website, the java applets on it, or the Vader Fader which I am trying to promote, please contact me. My E-Mail address is at the bottom of this page.
Other pages include ones on "The Web" where the author shares his thought on the world wide web: "As of now, the web is pretty small. Hopefully, it will grow into a larger web." It also has some things he made, like Pong Game, which lets you play a game of Pong, and download links for Vader Fader, a fader tool her developed for use with AOL.
It this really Mark Zuckerberg's old website? A lot of clues point to yes. The years match up. It shos the work of a precocious mind with an eye for developing useful tools.
