Chris Brogan's view is that the "junk" content available online will start to fall away during this year. I do hope he's right, it really isn't of any benefit to be barraged with content that is not of interest to you. 

However, I don't think he's arguing that content will fall in quantity over all; just that it will become ever more tightly-focused.  

This will pose interesting challenges for marketers in organisations with multiple specialisations, with a need to embrace technologies such as marketing automation services to ensure that the right content is suggested to the reader. 

One-size fits all publishing in an ever more specialised marketplace will make less and less sense.
