Love the standards. Valid XHTML 1.0 Strict FTW!
We like open standards, and we like writing sites "by hand", keeping complete control over the code. Besides allowing us to do exactly what we need to and exactly in the way we want to, when a human writes the code himself without relying on the shortcuts of some web design program, the code is more readable from other humans.
Most programs just write for the browsers, without caring too much about the readability of the code they produce: we care about it a lot. Pretend for instance that for some (unfathomable) reason you'll want some day some other developer to modify your website: if we wrote it, it will take him minutes to understand how it works; and probably a computer-savvy friend will be enough for minor changes.
Also, we never use flash - excepte for video player plugins, until new technologies spread - so the source code of every last bit of your site is always available for editing; we also have the good habit of putting a text alternative to every image, so that if someone is looking on google for some images on your site, he'll find it.
If you want to know more about the technical part, take a look at the programming languages / libs section.
We love using LAMP servers, and PHP is our server scripting language of choice, although in some particular occasions we don't disdain python or perl CGI scripting.
Nice things about PHP/MySQL when confronted with asp.NET: cheaper servers, since you don't need windows; better documentation; a cooler development community and, last but not least, you run Wordpress on it.
Javascript, and more javascript. Really, it allows you to do anything, included those things "you can only do with flash" according to popular opinion.
I mean, can't you just see how utterly cool this website is? Thanks to javascript, and the amazing Open Source library jQuery. And you know flash doesn't run on iPhone and iPad, right?
