I think he's describing the perfect digital news platform that I would think of.
It seems obvious - a lot of "news reports" nowadays are pretty much a couple lines of text with a bunch of tweets dropped down beneath them. But making that scalable is actually pretty difficult.
The first difficulty (and we've confirmed this and talked about the problem multiple times with directors of product at Twitter) is finding what the "best" stuff is.
We tried some time ago doing that for news - can we just algorithmically find the best tweets with regard to topic x? Even given full API access, the answer is either "not really" or "yes, but austenallred and his team aren't good enough programmers to figure it out."
There simply aren't enough inputs - it's the same reason Google has always struggled at real-time news. There are favorites and retweets, but those are largely a function of how big someone's following is. Some guy walking on the street taking amazing photos will never have as many retweets as CNN, even if you try to control for the number of followers, or measure retweets as a function of the number of followers somehow.
Then even if you could get that, the tweets aren't always analyzed in the right context. Run that type of analysis and the top tweet is likely to be a joke tweet or something like "OMG I'm praying for Boston."
The best solution that we can come up with is crowdsourcing the finding and curation of tweets. It's working OK, but there's a long way to go. Basically we let everyone find and submit tweets, tag them with specific topics, and then upvote/downvote and fact-check for accuracy. (for details on how it works, see https://grasswire.com/about)
Once you add a couple lines of text, you can turn the raw firehose of Twitter into something that can be consumed by somebody like my mom. That, I think, it a really big deal. It's working fairly well for news right now, and as more people join and submit it gets better. Our hopes are that we can expand into different verticals, and create daily digests of the best stuff with regard to topic x that you can consume in 30 seconds.
