Since this week's post on Monday a number of readers, old and new, have written to share their opinion on Serena Williams and the manner in which she "took down" the US Open for the double standard that exists between men and women in tennis. Here's few we've chosen to share.

When Serena Williams went on a rant last week about double standards at the US Open she did little to help the cause, other than remind us that when people of her reputation act that way...you usually get your way. And what's not double about that?

For years the NFL had a good thing going and then simply took it too far. They ran their stick in the ground and broke it off. Announcers who fear silence, and factoids with no bearing. Try to understand. I'm just tired of it all.

They say that bad things come in threes, and when they do come we’re seldom prepared to understand why. Which is why you live every day as if it might be your last.

In an odd marketing move on Monday, Nike Corporation chose fallen NFL star Colin Kapernick to be the face of the company in their new ad campaign. For the sake of 'sacrifice', they might have chosen better.
