Insomnia attack and a couple of hours of web roaming led me back here to re-read Eric's post #18 .. his take on relevancy.
The obvious pattern is that increased popularity leads to increased volume of media ... but the content often becomes redundant, sometimes to the point of same story/different byline.  All that noise makes it a lot harder to sift for the 'good stuff', the things that help create dedicated fans that will stay on the rollercoaster for a lifetime. 
And that is what you excell at KCortez, spotlighting music that moves you and making people care about it and the talented people that make it.  The stream of curious new ears will keep increasing so, whatever you decide is best for you, don't ever doubt that TIS is still relevant to GPN's continuing success!  Okay? ... just say yes ;)
