VIDEO: Twitter Moments among a line up of attempts to break into news business

Twitter made its long-awaited move into the news business this week with the launch of Twitter Moments, a new tab in Twitter’s mobile apps that let you see semi-curated summaries of the biggest news stories, as represented by things people are tweeting.

It makes sense, given that Twitter contains — among the 500 million things people tweet every day — an enormous amount of “news,” however you define that. But finding the news you’re interested in has historically been very difficult.

You need to spend a lot of time creating lists or following people who actually have newsworthy things to say, and even then, their smartest tweets are often mixed up with a whole lot of stuff that may be interesting, and even funny, but which hardly qualifies as useful information.
