I have a myspace, but my profile is set to private so only my friends can view it
There are loads of unknown people/strangers, especially bands that keeps on adding me as a friend almost everyday and I find that really annoying because I only prefer if people that knows me to be my friend.
The advantage of having myspace is that it lets me keep in contact with many of my friends, I have loads of international uni friends and friends that I made from the Expo, in this way I can talk to them once in a while so thats my reason of having myspace.
I do however have a facebook too. Facebook has less annoying people adding you as a friend, but most of my friends don't have a facebook, so I mainly use myspace.
