You are right, and the time is right too to start a website as myspace or youtube, or what's about a business portal as xing.com or linkedin.com? Are you still interested in partners?

A demo at http://pdndata.freehostia.com/demo.html is available, flexible software, which can be modified, used as e.g. business network portal or something else. It manages members, their data, a business and service directory, a blog etc. The things can be renamed, it's a database and content management system, template based, good to manage very different things.
