Mulltiple EasyBlog's

What is the best way to run multiple blogs on a single Joomla domain? The only way I see to do that would be to install multiple Joomla's each with an EasyBlog and place each in a separate domain. Then link the subdomains to the main domain to achieve a single site. Example:

Root domain Subdomain 1 Subdomain 2 Subdomain 3
domain.com subdomain1.domain.com subdomain2.domain.com subdomain3.domain.com
EasyBlog 0 EasyBlog1 EasyBlog2 EasyBlog3

Is there an easier way to run multiple blogs?

Thanks
