Twitter has taken a necessary evolutionary step in regards to its search function, by turning its search results into a real-time news and opinion aggregator.
Rather than be a list of updates related to the topic you’re searching, now it’s going to be a real-time data source.
For example: If you want to learn about swine flu, you’d search Twitter and turn up not only a list of opinions, facts, and news that people are Tweeting, but also information from the sites they linked to in their tweets–in this case it may well be other news sources, medical reference texts and so on. Similarly if someone tweeted a link to their blog post, you’d find data from that post appear in Twitter’s search results also.
This seems almost inevitable if you’ve ever used Twitter as a source of news information.
