Some of the interesting ideas from the video regarding Twitter:
"Twitter is for old people, is the attitude of many young people."
"Twitter allows users to connect with people anywhere in the world, and carry on a conversation."
"Trying to get to the dis-information on social media networks is problematic. Individuals or companies can create false identities to communicate information."
"Interesting period of time when social media is losing its innocence."
"Use common sense about who you follow on Twitter. If they have a 'Jack-the-Ripper' avatar, it's probably not a good idea to follow them."
