There are many pluses and minuses to the amount of information available to us on the web. We are able to be informed much quicker about events, without having to wait until the evening news for the whole story. We are able to hear the stories from eye witnesses to happy or tragic events when they post blogs, or even just update their stauses on facebook or twitter. There are many websites where you can have discussions about events or you can watch it happen on youtube.
Many people credit the information they see on the internet as fact. The bad thing about this is that it could be someone's opinion and therefore the reader would gain information that is biased and would unknowingly agree with this person. Although people can pick and choose which information is true, the ones they choose could actually be incorrect. Some websites could look professional and legitimate, yet still be comepletely incorrect or biased. Another bad thing about news being on the web is that news becomes old much quicker than it does on television. Newer stories become much more important and people could be uninformed about new things that are happening for past events. For example if there is an earthqueake, the story may be interesting online only for a few short weeks because somewhere else a volcano errupts, and the earhtquake victims are forgotten. This does happen on television as well, but the earthquake story would still be in the news, just not the "main event".
I think overall that the quality has infact decreased. I find that these days people who post news online talk mostly about what they think about it rather than just stating facts.
