What are the advantages for two different blogs to share a WordPress database; what are the advantages for two different blogs to have two different WordPress database files?
Background. I have two fully hosted domains that will each be a blog. My web host has downloaded WordPress to the first domain. When I began to set up the second domain, I had to choose whether or not to establish a new database or use the one I just created. I have not been able to find any documentation with a rationale for sharing database for both blogs or creating two separate ones.
