have come to accept from the moment I signed up on Hubpages I may never see any of my articles featured. Hubpages motifs on deciding what gets featured may not strictly be profit related. They're protecting their own skin.
Most of the featured articles are using topics that are conventional and safe in nature. Basic "how to's", "what is this/that", and "how this/that works." Nothing that you couldn't find in wikipedia, an encyclopedia, etc. If you want to get featured be prepared to write some articles with the following rules:
A) Conventional topics people tend to read: pop culture, media, child raising, cooking, maybe some outdoor activities, etc.
B) Non controversial: Hubpages doesn't want to held liable or looking like they're promoting the views of a given author. So, controversial Hubs will never get featured.
C) Safe writing styles (stay academic): Definitely don't use any "I" statements, cite everything, deliberately make the article anal (definitely don't use the word anal).
D) Stay unoriginal and keep your fingers crossed that somehow you're noticed out of possibly hundreds of the same unoriginal Hubs on the same popular topic.
