None of my complex, multi-paragraph, polysyllabic, literary hubs has ever been approved by AdSense. They told me I did not have enough full sentences, lol, when every Hub is basically brimming with full sentences.
As I believe Elvis Costello once said, "I used to be disgusted; now I try and be amused."
I'm going to continue to produce philsophical, ruminative hubs for the pure joy of producing them, even if AdSense does not deem them worthy. :)
