Seen the iPhone 4S commercial demonstrating Siri and wondering how to get it to understand relationships so you to can say things like "Call my wife"? You can always add relationships through Contacts but it's much easier to just get Siri to do it for you.
Now if you have more than one brother (I don't) - you'll probably need to specify a bit more. You can use things like "oldest brother" or however you want Siri to distinguish people. You can also remove relationships from within your own contact card as well if you need to.
Once you've got the relationship defined, you can tell Siri to do really cool things like -- "Tell my brother I'm running 15 minutes late", or "remind me to change the lightbulb when I get to mom's house".

UPDATE: To get the most value out of relationships, you need to be syncing contacts with iCloud. Exchange, including Gmail over Exchange, only supports a few kinds. (https://twitter.com/theiblog/status/126302803978235904)]
