When is too early to FB?

I have a modern dilemma- one of my son's little buddies wants to "friend" me on FB. I'm thinking...no......Nooooo...NOOOO! (or at least not until I get my privacy settings really fine tuned.)

Anyhow, I'm thinking 9 is awfully young to have a FB account- (thankfully my 9 year old has no interest in Social Media, yet...but it's coming!) What do you think? is there a "magic age" when social media use is appropriate? 

I almost always err to the side of keeping my child innocent as long as possible, limiting computer use is at the top of my list.

Nooooo, I'm not saying that using computers is bad (that would be pretty hypocritical of me, FB group girl) I'm simply trying to get an idea of how my son's generation is digesting modern technology.

new computer

I now have a new computer. Not that I was in the market for one..

I got one by default after someone (not me) spilled a cup of tea on the keyboard of my laptop.

Now , after  A week of trips to the computer store, angst , tossing and turning and grumbling I am faced with a weekend of learning how to use a Mac. Yup, I made the switch. I had heard so many negative stories about Vista that I refused to be forced to get another pc. 

so....we will now see what all the hubbub is about bub.
