Used mine to post meaningless stories about absolutely nothing, whatever was on my mind that day. I guess you could say I used to blog, facebook, or tweet before those terms became popular. Of course, I had the mandatory overly-busy repeating backgrounds, poorly-written javascript, and after a few months, all the other webpages I linked to went down (so many other free hosts fell by the wayside).
I also uploaded my latest C++ projects as I completed them in high-school. I don't think anyone ever saw my site, I set my own counter to 1-million hits, and I think it had 1-million and 10 before I stopped updating it a year later.
