With my limited background, judging the quality of a link (when they work) can be difficult and therefore, I willingly rely on sites (
like this one) that offers
curation using some «smart» aggregation
tools of the legal trade.
If it really wanted to, Twitter could not only use its own algorithms to generate aggregated content in interesting ways, it could start to accumulate a suite of
tools that allow users and even journalists to do the same — whether it's something
like Storify or Storyful (which has a paid - for Pro version that helps media companies verify and fact - check the content they are collecting) or another
curation / discovery service
like Prismatic or Percolate, or even a consumption and recommendation app
like Flipboard.
