It doesn't help much if I avoid Twitter, when all the major news media outlets think that Twitterers are the vox populi, and use it to source their articles.

The corollary is to avoid any source of “news” which does that. Stick to written media in most cases, avoid lifestyle pieces and minimize your exposure to politics. When possible go for primary sources on foreign affairs and cross-reference several viewpoints. Most of all don’t spend too much time with the news, especially the “major” outlets because they’re just poison.

This is lazy or mendacious journalism.

A few Tweets are quoted to give the impression of widespread outrage.

Tweet embedding is a negative value feature that’s helping to corrode regular journalism, and that seems to be of very limited value.

this point was made in, of all places, an episode of Parks & Recreation in 2012 where the moderator at a political debate has to read out a typo-filled question posed to the candidates, and remarks mockingly "and this question is from Twitter, which is something we are apparently doing now".
