Sure, as it relates to learning various web development languages and techniques, there are a variety of sites and resources.
But as some of them are beginning to fall out of date, it’s worth tracking the more relevant newcomers for resources and inspiration.
TutorialZine is a website that provides tutorials on a variety of web development related topics.
Some of the resources are as simple as basic CSS information. Others are focused on technologies such as Google App Engine or building custom Ajax-enabled jQuery plugins.
Anyway, the site’s got a solid presentation and is worth an RSS subscription or bookmark if you’re looking for a useful resource.
