Facebook, Vs Mobile Phones Vs second life?

In times people use different ways to study and I have found that people tend to use more of a computer approach.
Facebook can help with studying as it is a social networking website where people can create groups so people can get together and compare notes, have discussions and upload work through images but there is not personal contact.

Mobile phones, mobiles nowadays with growing technology of videos, cameras, texting, video messaging and picture messaging can help as now students can do work but its also a distraction.

Second Life is now a new concept which has been around for a while but only recently been modified and updated to be more sophisticated. on Second life you can create an avatar of yourself and create an environment similar to yours but nothing is different jus the way you design it, on second life you can use this to study and this is because creating groups and islands here you can invite students and you can hold virtual lectures online.
