I've seen mine do the following:
1. The vast majority (especially political pages) have a relatively short shelf life, relatively few views, and fade out to relative nothingness over time. So, maturity for those is not a factor.
2. The ones that stick around and build to a point of drawing daily views EVERY day are presumably the ones that make a few bucks here and there. (I don't track their money making stats, but it makes sense.) For those, it's really variable.
Example: My top Hub to date (in both views and, presumably, money clicks) is titled How to Build a Survival Cabin on a Shoestring Budget. Google and the other search engines always did like it, and almost from the beginning it got at least a few views daily.
But that changed dramatically with the advent of a comment left by Red Elk, who also builds survival structures--some of them quite remarkable. We began tossing comments back and forth, and the massive commenting action seemed to be the biggest turbocharger a Hub could have.
When Red Elk (who has become a close friend) first showed up, the Hub had been published for more than a year and was averaging maybe 10 views a day. Since that time--it's now been online for four years--it's grown and solidified on the Internet to the point that 100 views a day is a slow day. Also, all you have to Google is "Survival Cabin", and the Hub will usually pop up in the #1 Google results position (after the paid slots at the very top).
Summary: "Maturity" is good and yes, does make a difference. But in my experience at least, (a) longtail niche title and content and (b) commenting activity are just as key, if not more so.
