Hi 5?

I sent out some Gmail invitations and Wallop invitations and Huminity invitations, and now I got invited into Hi 5 too. There're too many SNS(Social Network Service)s right now, and I'm sick of it. Actually, I didn't answer the invitation of Hi 5, and I quitted the Huminity. They are good societies, but you can't just stay on-line all day long to make friends in the Virual Network, you got to go out and play soccer sometimes.
