Advantages of Microblogs

  •  Good for sending fast, topic-related alerts (maximum 140 characters) to interested subscribers.
  • Good for driving subscribers via shortened URLs to online content where they can find more information with greater context (e.g. latest news, updates and publications).
  • Despite the medium’s character limitation (140 characters), it offers the opportunity to engage immediately with a very diverse audience and share information flexibly.
  • Use of the hash tag (#) helps to situate an individual piece of information within a broader conversation and allows this piece of information to be easily found by browsers searching for information on the topic of interest (i.e. the ‘tag’), e.g. during the German EHEC crisis, ‘#EO104’ was commonly used.
  • Domain experts, journalists and the general public are likely to use microblogs both to communicate their views and to source information.
  • Twitter is a hub of information that spreads across networks.
  • Research has shown that Twitter is one of the main channels used to communicate about food risks/crises.
  • Useful channel for monitoring sentiment, testing concepts and assessing people’s perceptions and responses to events.


Disadvantages of Microblogs

  • Characters are limited and fragmented conversations might not facilitate meaningful dialogue.
  • Never know how far a tweet can go (or not).
  • Twitter presumes a lot of responsiveness.
  • Tweets cannot be easily retrieved a long time after posting.
  • Easy to attract criticism on Twitter (which in the right context can turn into an opportunity).
  • Inappropriate for obtaining in-depth feedback on issues.
  • Individuals can be faced with information overload on Twitter during crises because of the ease of onward transmission.
