Cybernetwork swamping

Anyone else feel swamped by all these "friend network" sites? I understand having one or two of em but come on.......an invitation to join a different one everyday? You must be kiddin me.

First it was friendster, then hi5, myspace and sms. Yeah I joined all of these, played with em for a week or two, before moving on to other stuff. I barely know one-quarter of the people on my friends list. Seriously whats the point of this? Yesterday I got an invitation from a friend inviting me to join zebo. Zebo? WTF is zebo? Browse your friends' shopping list? Screw you, I don't wanna browse my friends shopping lists. Just leave me alone.
