Due to rapid development and spread of social networks, politicians among other public figures were forced into also using them to communicate various things (e.g. Trump's Facebook account, Trumps Twitter account)
Question: do posts made on these networks have the same power as public declarations made using more classic channels such as TV broadcasted press conferences?
I mean do they generate the same reaction? e.g. diplomats ask for clarifications when an important politician makes inappropriate allegations about some aspects of his/her country. Or some messages are simply ignored if not made using a classic way of communication (e.g. posted as official announcements or documents on Government's web site, TV broadcasted).
I will try to clarify the question by providing an example. Trump has posted the following message on his Twitter account:
The U.S. has been talking to North Korea, and paying them extortion money, for 25 years. Talking is not the answer!
This is clearly related to North Korea, and its relations with US. Does this kind of post/message creates the same effect as if it was said during a press conference, a summit? Or these messages are seen as less serious if a social network in used as a channel?
