I joined Twitter because I am an Africam watcher and it has been a great tool for that.
I get a notice if there is a leopard, lion, cheetah, rhino, jackal, hippo, giraffe or other wild animal at the waterholes and can check in instead of having to watch the screen all the time.
Other than that I could do without it.
FB has been good for seeing pictures put up by my son in Iraq and also working on a high school reunion.
May all beings give and receive compassion, Live free from fear, And dwell in peace. - author unknown
