I did some really basic website stuff back a few years ago, but have recently gotten back into it and have kept myself busy learning html, xhtml, and css. i feel like i have a solid understanding of the previously mentioned technologies, but i'm just wondering on what i should start learning next. right now i'm eyeing XML but i dont think i have any applications for it, and i'd just like to see what you guys think.

Next thing should be PHP or ASP.NET. Any kind of serverside language.

good deal. there seems to be a ton of free tutorials on getting started w/ php. you have any particular suggestions though?

PHP with MySQL tutorials. It's always good to know how PHP connects to a db.
