The worst example being media organisations. Why would you cede any remaining semblance of journalistic authority by cheaply embedding tweets into a news article. Handpicked commentary from a narrow part of the internet does not constitute an expert opinion, nor does it lend you any credibility. If anything, it lets me know that I’m seeking news in the wrong place. The short term gains, if there are any real ones, seem to be obviously outweighed by the negative impacts to your reputation as a news organisation.
