     Have you got a Facebook account? Are you thinking of getting one? Jamie Simmonds has just signed 
up. Let's see how she's getting along.
                                                                     My Diary
     MONDAY:
I'm officially a Facebooker. I find a few people I used to know and I've soon got seven
friends. I've never felt so popular! I wonder if my old university flatmate Steve is on here…What do you
know! He is! Maybe Facebook has its uses.
     TUESDAY: I've received lots of nice welcoming messages on my wall. Later, I meet up with Steve
for a drink after not seeing him for five years. We get on really well! Then, he uses his Facebook app for
iPhone to suggest me as a friend to some other former classmates. Some of them even come to the pub
and it's just like old times - possibly a bit too much like old times. During the night, photos are uploaded to Facebook.
     WEDNESDAY: Disaster! My mum's on Facebook! Has she seen the photos of me dancing on the
table from last night? Has she shown them to dad? Oh. And I have a friend request - mum again!
     THURSDAY: There's a message from my boyfriend, "so, it's over then, is it?" Evidently I haven't
changed my settings to show I'm "in a relationship", and I haven't even added him as a friend. Ah, well, I
wonder what my ex-boyfriend is doing… Whoops! I accidentally type his name into my status box instead of the search 'oox, and now every one can see it on their news feed.
     FRIDAY: rime to update my status: "Work is boring. Can't wait for the weekend!" Yeah, that about
sums it up. Oh, look, I've received a comment! Someone must feel the same way. Lots of my friends now
"1ike" this status.
     SATURDAY: Good news! I've got 100 friends but wait! Someone's "un-friended" me! I look through my "friend list" to try to work out who it was. Why did they do that? Am I really such a terrible person? I
never knew Facebook could be this cruel.
SUNDAY: Wake up. Check my Facebook page. Make coffee. Check my Facebook page again. Get
ready to leave. Change my mind and check my Facebook page …
