"keeping in touch" with a valuable person to one's life would always be the significance of those so called friendsters, facebooks, blogs, etc. this is very true but i am just wondering if these would promote quality education. In some cases it could be an aid specially to those who are fun of sharing ideas and as a prospective English teacher in the near future, i would intently recommend English as the medium for communication.
Another importance is that these methods of networking provide many simulations and games that could be used for brain enhancing and wisdom giver.
Yahoo.com, and google.com are also available not only for communications but also as a resource of knowledge like an open encyclopedia in which it tackles everything.

Technologies are really great!
Internet Explorer is now very useful, mozilla firefox also is widely known.
It's time to make a change..In computer education, be get involved!!
