I should also add - please post any recommendations re: sources to cover.
- how often do their stories become members of clusters? - how "fast" are they to publish on a topic vs. other competitors - i.e.: who "breaks" the news? - what tags (people, companies, topics) does a given source stick close? Which do they shy away from?
Thanks very much for a really interesting set of ideas to explore!
Note that the top news breaker is: The Verge, having broken about 10% of stories on my site; TechCrunch is next at 8, followed by ... MacRumours at 7.
