Is there a free or cheapish script thats simple social networking, like the others, friendster, myspace, facebook etc but has the function that wayn has where you can pay to upgrade and get more features available to them?
If your host offers Joomla, there is a free extension available with basic social networking functions. Addons and plugins are available, but I guess it just depends on what you want from your site. Check joomlapolis.com.
