Hi,
The easiest way to fix this issue is to assign the blog app to a different application pool. I don't know if GoDaddy will let you do that or not. You may want to consider dropping GoDaddy and going with a host that actually conforms to standards. ;-) You can see a list of hosts that should fit your needs here: http://www.mojoportal.com/hostingpartners.aspx.
HTH,
