I watched Twitter after EgyptAir flight 804 was lost. And I was amazed by the amount of shit I got to see. Everybody was placing assumptions, unknown 'facts', stupidity and so on.
Sometimes I saw a relevant post but then it got reposted a trillion.
Maybe some streams are of good quality. But my breaking news experience was not of high quality I must say.
This sounds weird to me, because Twitter seems the epitome of quantity over quality.
Even with my carefully selected RSS feeds I feel overwhelmed by all the news I get in a day. I can't imagine following news on Twitter where people think it's perfectly OK to post a new tweet every 10 minutes.
Unfortunately, in an effort to satisfy undisciplined people that routinely follow people in the order of thousands, each one of Twitter's tentative change to incrementally bring a mimicry of automated smartness to everyone's timeline has terminally ruined it for me as my feed turned into a non-deduplicated, unordered mess appended with nonsensical suggestions (and ads).
