Subdomains? You mean like blogs.lautier.com, messageboard.lautier.com etc?
I can't see that that has anything to do with it.
If you are nervous that the bloggers would slow down the message board,
then the same or the different database does not matter, as long as they
are on the same server. And that would be an argument for different
databases: if you go for different databases from the start, it will be
simple to move the databases between servers.
But then the databases would be entirely independent. Things like storing
users and their profiles should probably be in a separate database, and
the middle tier would be responsible to pass that information to the
databases.
