The goal of any news delivery medium is to provide maximum signal-to-noise ratio to its target audience. “Signal” is the set of news items that is of interest to a person. “Noise” is everything else. The reality is that an infinitesimally small percentage of news is interesting to any given person. And that percentage is shrinking every day because more news is being created on a daily basis: more frequently are more people documenting more people who are doing more newsworthy stuff every day.

In order to keep SNR high, news mediums need to focus on the news interests of their audiences more intensely than ever before. However, trying to create a single focus for a group of individuals, each of whose interests differ somewhat, is not a long-term solution. Sites like PerezHilton.com, a leading Hollywood gossip blog, and TechMeme, a leading (especially here in the SV) tech news aggregator, provide a certain segment of the news to an audience specifically interested in that segment. However, over time, the amount of news created in the news segment grows and the the segment bulges. The news publisher either must choose to further narrow their segment, which will alienate some of their existing audience, or publish a higher volume of news, which ultimately lowers the SNR to any given audience member. Either of these options is not a good choice.

Long-term, the only news deliver medium which is viable is the roll-your-own news concept. Geeks here this and start throwing out terms like RSS and OPML but the bottom line is that you don’t have to know technology in order to determine whether a piece of news is interesting to you. Over the past months, I’ve found myself going to news sites, including TechMeme, less and instead refreshing Google Reader more. I’ve added many feeds and the news that arrives is astonishingly interesting to me. Most importantly, my Reader is astonishingly uninteresting to most other people. This kind of relevance is ultimately impossible to achieve by any news publisher that tries to appeal to more than a handful of people.

I don’t want you to conclude from this that I think the penultimate solution is the RSS Reader. The concept of explicitly adding feeds to a reader is just not going to fly with mainstream folks. So what is the perfect news medium that allows you to roll your own news but doesn’t require any tech savvy? Attempts have been made (NewsVine, etc..) but I think we have yet to see the killer news app.
