The power of the internet is that everyone can be a journalist. The downside of the internet is that everyone can be a journalist.
The power of internet is that speed upon which people get news from any event. The downside is the speed. People get used to speed, and that creates cycle to create news fastly, which then can lead into incomplete, potentially erranous news.
The competition to get news out is the new goldrush. This means having news is the news. Speed over content. Correctness, truthfulness of them is seconday, and if there are any corrections, not many read those - corrections are not news anymore. If people spend time to send the corrections, the writer tends to add the correction in a form "n.n send this: blahblah" - aka not admitting the mistake on the first place but pointing out someone sending it (this is same as saying "sorry if i have offended anyone" - the word "if" points out not taking responsibilit) and bringing totally outsider into a limelight. Admitting mistakes would be crucial to gain trustworthiness.
