This happens to new technologies too. I was alerted to this short video (part of its online explore section) via a colleague on twitter.
Twitter continues to be a technological phenomenon that divides people: and that is how quite as it should be. If you cannot see its potential, then that potential is probably not there - for you. Perhaps you recognise that twitter will be only one more diversion from your studies and you cannot really afford to be distracted right now (or ever). Or perhaps twitter is a thing with multifaceted potential: potential to alert you to wonderful online resources, potential to bore & annoy you, educational, informational potential. You must make up your own mind, possibly through reading, listening, watching, discussing, and thus taking part in an old debate about technology: good or bad or neither or wrong question?
This question about technology, whether it enslaves and alienates us or "sets us free in a democracy of education" was debated 40 years ago by Norman Mailer and Marshall McLuhan and this morning, BBC Radio 4 revisited this debate in a 15 minute episode of "Head to Head". You have 7 days left to listen to it again.
