How secure should our MySQL settings be?

[Jeff]

For the first time recently, I set up a couple of apps in my server space here that use MySQL. Since each new database requires a username and password, I'm curious what the ramifications are of those being compromised. If the data in the database isn't particularly sensitive (like RSS news stories), are there other reasons that I should be be concerned with making those usernames and passwords hard to guess?

Most usernames are used for both reading and writing. If you don't mind taking the chance that someone could "deface" your site by making/replacing entries in the database, then passwords really don't matter, do they?
