The World Wide Web (or 'www') is so popular and widely used that it is often confused for the Internet itself. Borrowing Al Gore's analogy, if the Internet is thought of as a highway, web sites could be thought of as destinations along the way. Each website has its own purpose: there are websites for reading, websites for answering emails, even private websites (somewhat confusingly called Intranets) for people at a particular company.
While some websites statically display information (a bit like a billboard along the highway) the real power of the web is seen when a web application dynamically responds and changes based on input from the system and its users.
At Mutually Human we build web applications. In contrast to static sites or brochure sites, our applications focus on interactivity and serving a function. Rather than a series of pages or Burma-Shave style advertisements, web applications allow you to interact with full-featured software over the internet.
