I've written enough code to be compelled to start off with "Hello World".
However, I haven't written a line of code in something like 20 years at this point (maybe more), so pardon my dust while I remember how all of this works. And, yes, for the moment, that means the site is almost certainly going to have all the design sensibilities of the most basic mid-90s webpage (ie, there will be no design). For now, I consider this my homage to to when Netscape Navigator was the New Hotness.
I never had a Geocities page, personally (I legit don't remember what I had - probably some random nonsense on my college's student server.), but I'm delighted that Neocities exists. I don't know that I'm going to be able to really maintain a website (I've never really managed it before), but we'll see.
