I think social network sites for youth are educational because when stay online and chat with their friends they learning english words even though the they are using short form such lol and Imao those type of words even me I use these type words when i chat with my friends because I am too lazy to type the full word so I use the short hand when I chat with my friends online.
It is interesting to see what your friends are writing on your bebo and facebook that is why I try to check my messages everyday and I think everyone who uses these sites feel the same way like I do because are communicating and learning the second language through chatting and emailing message to one another especially the teenagers who chat with their friends are learning the second language.
I strongly agree that network is an educational tool for the youth and adults because as a Cree person I have learn new words through online network sites and i also learn how to work and create eductional curriculm using a computers and the most important thing I that I have learn through a computer is my mother language it helps me to improve my own language this why I strongly believe online network is good educational tool for the youth and us the adults to learn a Cree syllabics go to eastcree.org
and www.eastcree/keyboarding.html these websites will help to learn Cree language.
