The thing that we found performing the process manually is that some of the best content comes form people with a couple followers, so there's not enough data (retweets, interaction) to determine what content is quality. Our proposed solution to that now is just to show everybody everything that matches a certain keyword, similar to the hackernews or reddit /new feed.
Interestingly enough there are some people doing this already, just without a tool. So they'll watch the networks all day and gather links into google docs, fb pages, twitter, etc. It works really well, but it's a one-man team, and it's a very painstaking manual process. We want to let more people contribute to that same process, and eventually (hopefully) entirely crowdsource breaking news.
Yes, and almost equally important (at least IMHO) would be providing a record of what happened in the past. A way to find every piece of news surrounding an event. For example if I want to see a full outline of every Snowden related article I could pull them all up and then filter down to just news articles that were first to publish a particular story. While I am sure there are people creating pages/full websites to document this one issue I would love to have that for every event so that instead of endlessly googling for articles related to something you could just got to Grasswire (or other site). Sort of a Wikipedia for events but built from sources instead of written by people who then link to sources.
Functionally I also cannot seem to scroll to the bottom of the tweets, and I would fix the loading on the main page. The news articles are loading on the left side of the screen and then shifting to the center.
