There is power in the hardware used by a computer, but there is more power in the software that is used.  Web 2.0 came about through a .NET development company that applied the technology and tools needed to power this great application.  I remember when it first began and I have watched it grow.  The development of Web 2.0 was ingenius and is being used for entertainment and fun on the Internet.  Social networking is one place you can find this technology.  The tools used include Joomla CMS, PHP, JavaScript, AJAX and XML.  These tools and technologies allow the users of such websites to interact and grow their own communities through blogs, forums, profiles, photos and chat.
