Digital Journalism Review | Digest: Is Twitter a "media", or just a platform for media?

It is no doubt that Twitter has become one of world's best platforms to share real-time information. At the same time, it also makes money from selling ads, just like media outlets do. So, it will be interesting to see whether it wants to move forward one more step to make itself a real media company that not only “share” but also “create” content.
And, if the answer is “yes”, will Twitter be a new threat to traditional news organisations?
Fortunately, according to what Twitter CEO Dick Costolo has said (see article here or below), their focus is still on bettering the information-sharing platform and providing more useful functions for journalists.
Twitter knows that the increasing number of journalists and news operations are making it an important channel to promote their digital content or collect information – and Twitter is offering more help with this. But can journalists really take advantage from the new tools? I’m still not sure about that.
