Good question... didn't even register that there was a Hub of the Day... thanks to Tussin for the link.
Personally I wasn't to pleased with the rules... I think of Hub Pages as a place for Authors... a well written Hub, on a timely subject, a beautiful poem... this, is what should be the #1 criteria. All this importance on having pictures at all, eludes me... especially when linked to so many rules.
Grammar is in the eye of the beholder... I can and do write sentences that are a whole paragraph long ...and so can any Judge, and the Supremes can do it double time. Apparently, unlike the most brilliant writers in America... a simple Subject, object, etc. is what counts. Maybe I mis-understood.
