Twitter Really Does Break News

Twitter isn't a very good "search engine," many would argue, but there are reasons for that.Twitter really is becoming a place where real-time news breaks. But that also means a high degree of content churn. 


The most frequent terms in one hour might look very different from those in the next hour, . Twitter says. 


Examining all search queries from October 2011, Twitter found that, on average, about 17 percent of the top 1,000 query terms from one hour are no longer in the top 1,000 during the next hour. 


In other words, 17 percent of the top 1000 query terms "churn over" on an hourly basis, Twitter says.


Repeating this at a granularity of days instead of hours, Twitter finds that about 13 percent of the top 1,000 query terms from one day are no longer in the top 1000 during the next day.


But during major events, the frequency of queries spike dramatically. For example, on October 5, 2011, immediately following news of the death of Apple co-founder and CEO Steve Jobs, the query "steve jobs" spiked from a negligible fraction of query volume to 15 percent of the query stream.
