Since killing my account (because they kept resetting my privacy settings to public... bastards) I've outsourced my Facebook Birthday/Party monitoring to my girlfriend.

It's risky to own lots of stock in your employer because you losing your job would be more likely to come at a time when your investments were worth less. It's risky to let your SO handle too much of your social life for similar reasons.

I'm very close to my wife and can't imagine getting a divorce, but I think it's healthy that we manage our own social calendars.

I'm similar to BWStearns, I let my girlfriend monitor facebook for events, we often both get invited to events where only one of us attend or one of us is invited by the other isn't. That's not to say she manages my calendar. We have both our own GCals (viewable by the other) and a shared GCal, we've had a long standing agreement that if we book anything in our own calendar attendance by the other is not expected and our shared calendar is attendance optional unless otherwise specified.

Not to be totally pessimistic, but that's probably potentially even more dangerous than trusting all that data to Facebook...

I didn't mean to imply maliciousness -- rather to draw a line between the sorts of friend-of-a-friend-of-an-ex-coworker parties you might miss out on for not being on Facebook, and a party of an actual friend you know and spend time with.

In short: pointing to the line between friends and "friends" and (likely my personality coloring the value judgment) thus questioning whether you're actually missing out by not being so closely connected to those "friends".

(Frankly the very concept of a house party with so many attendees that don't actually know one another, that a door man and a guest list is required, sounds like a caricature of a straw man I might have cooked up to have a laugh at "things you might need FB to get invited to". But maybe that's just saying more about me and why I don't grok or value things like FB.)

I've talked to a few people who were sending out their wedding invitations and were legitimately worried about accidentally missing someone on their Facebook friends list or forgetting about someone who doesn't use Facebook.

It's definitely naive to think "oh, if you're really friends with them you'll remember their name without the help of a computer." This is especially the case with larger more inclusive weddings where now-disconnected friends are invited.
