Overview of citizen journalism...

Citizen journalism is a part of people from the public, who is active in discussing and reporting issues in the society.
When the England subway bombs exploded, the BBC news reported this incident not only by collecting the news from professional journalists, but from the public as well. Therefore, the reporting could be more believable and comprehensive.
The advantages of Citizen Journalism can be seen clearly from this event. The groups of people from the public helps news reporting to be more perfect and the newest, while they takes a part in reporting which the public has rarely done before.
As I see that in China, some of the local newspapers have already welcomed residents to report news happened around them. Thus, the newspaper could vary content.
Although the news which reported from the public may include mistake or grandiloquence, overall, it is good to see that the public cooperates with the professional news area.
