Network for disconnecting people

Why would you check somebody's status in your mobile rather than calling them and asking how they are doing? I would feel very happy if my friend call me and ask about me rather than being poked in Facebook.
We can browse Facebook in our mobile and myspace just announced that it can be now available in mobile phones also. The news can be found at http://www.vnunet.com/vnunet/news/2199455/myspace-launches-free-mobile.
For me it is very unlikely that I browse my friends profile in my small cell phone. I like to use facebook and myspace, they are a good timepass, but they look good when you can browse stuff in your wide monitor notebook. If I don't have a computer and I want to know how my friends are doing I would rather call them than looking at the small screen of my cell phone.
Web in mobile is good. When we are in the middle of nowhere and want to google something, it can serve as a good tool to find information. But browsing facebook or myspace in mobile is a little too much for me.
