According to wikipedia 96% of tweets are not news

I don't use twitter for news because I don't care to sift through the 96% of drivel people seem to put up there. But your saying people actually do that?

How do people find good context on twitter? Do they follow people who only post good news type stuff along with their boring friends?

When you want news, go to the profile of a news organization, not a high school buddy. If you want a stream of tweets, put a couple news organizations into a list and read the list. http://twitter.com/#!/reutersflash http://twitter.com/#!/skynewsbreak
