Physicists Find Users Uninterested After 36 Hours

SuperGrads writes "Statistical physicists working in the US and Hungary have found that the number of people reading a particular news story on the web decreases with time by a power law rather than exponentially as was previously thought. The finding has implications for the study of information flow in social networks, marketing and web design."

maybe because it's not "news" anymore?

I'm wondering if these same researches tried to define what their subjects defined as "news"? If something was newsworthy, I'm guessing they likely found out about it over time. Maybe the people didn't read it because they were informed from other sources?

Sounds like a bit of a flawed evaluation to me.

Wow. It didn't even take that long.

But seriously, I wonder if this will change ad placement for revenue models? If an ad gets a click on a story older than 36 hours, is it worth more? Hmm, I smell a patent in the works, too.

Methodological issues?

I've read the linked article but not the actual Phys Rev paper, so I'm likely blowing smoke but...

• The "news cycle" is 24 hours, due to historical roots in daily newspapers (augmented by the evening news, etc.) Assume for the moment that people stay interested in a news story. After a day, if the story is ongoing, the original article is likely to be replaced by an update. Real-life example: Over the weekend, the NY Times Science section had these stories in a row: "Shuttle astronauts complete spacewalk", "shuttle astronauts inspect tiles", "shuttle Discovery meets space station", "shuttle Discovery set for launch". (paraphrased) Clearly, the first story in the list is the most recent and, were I looking for news on the Discovery, I'd probably click that one. Even if I really liked the Times' coverage of the rendez-vous, I'm not likely to read that article again if a new one has been posted. Does that mean I've "lost interest" in the shuttle?
• The results seem drawn from traffic at a particular Hungarian portal and might not have any generalized relevance.
• Ease of navigation seems important but not addressed. If stories "fall off" the homepage after 36 hours, it would make it look like people were less interested. (Or, really, the fact that some stories are highlit on the front page makes it look like people are more interested than they really are.)
