Steve Gibson actually mentioned this, me, and my blog post on this and the mod_status 'vulnerability' on big servers in his last Security Now podcast. Doing what I can to save the Internet, lol ;p.
I noticed OpenDNS has extended capabilities you can turn on or off. You can choose to have it log your DNS queries, so you can see what sites everyone in your household is visiting, for instance.. block sites.. or you can have it not log ANYTHING, and it says it throws away all DNS queries. Of course, I opted for the latter, for privacy. That said, I'm not too concerned about anyone knowing what sites I visit, but I still like my privacy. At least this way you've got your DNS separate from your ISP or Google, and encrypted to protect from Sniffers. For these features you must sign up for an account, which also offers a DNS client to update your dynamic IP address at home (so it can track you if your IP address changes).
Don't bother signing up at all (even for their normal service) and you're probably most private, as their DNS servers (plaintext and encrypted) are open no matter what.
