Pros – through the use of social media, a politician is more
accessible to his or her constituents. If someone has a question or a concern,
he or she should be able to directly address the politician. And a politician
will be able to then respond as well. It improves the contact be those who are
governed and the ones who govern. The internet allows for immediate contact in
multiply directions.
Cons – messages can be numerous and/or one person may be
unable to respond to a significant number of his or her constituents. There is
no real accountability for people who use fake accounts and then attack and/or
spam the politicians. As it allows for people to express themselves with
immediacy, some people may frequently react emotionally, instead of
thoughtfully.
Social media allows and encourages genuine discourse and discussion
to occur, but as with everything it depends on the responsibility of the users
to use it effectively and with honest purposes.
