Noise on the Web
There is a lot of noise out there on the web. But one man's noise is another man's signal. Generation Y types know how to filter the noise. The rest of us having come from an information scarcity background. Remember the days when we use to file periodicals for future reference? Filtering what you need to know from what looks interesting is critical if we are to avoid drowning in content.
This presents a great opportunity for super niche information aggregators that identify communities that are willing to pay for high signal to noise content.
