    Twitter ist vor allem ein Kommunikationswerkzeug und entfaltet häufig im Verbund mit anderen Werkzeugen seine Stärke. Twitter dient zur schnellen Information, dient als Feedbackkanal und ermöglicht den Austausch der Teilnehmer untereinander. Twitter ermöglicht * Ansichten und Gedanken zu äußern, sich Inspiration zu holen und laut nachzudenken. * Diskussionen und Trends zu verfolgen. Man bekommt mit was auf Veranstaltungen läuft und über Twitter und Twitterwalls werden Meinungen gebildet. * Fragen zu stellen und Feedback zu bekommen. Kontakte zu Experten können ohne formale Barrieren geknüpft werden.

  • Our own Jacqui Cheng suggests a variation on this: make all laptop users sit in the back, so that they only distract each other, and let them figure out whether their grades are suffering on their own.
