Default ext3 Error Behavior

I'd like some insight as to what the implications of setting the ext3 error-behavior flag to continue.  I believe by default this option is set to remount read-only, what is this really protecting against?

My application requires keeping a single OS up if at all possible, and minor log data (the only thing being written to the disk) corruption is acceptable.  What I do not want is a single write error causing the filesystem to be remounted read only.
