Not sure I agree.. maybe shame and shyness are being conflated here. My read of the article was that this shamelessness was in context of society at large -- kind of sociopathic almost.
In dating, there is no shame that way -- it's a perfectly acceptable behaviour many people engage in.
I haven't seen it having a "flare" effect like the article mentions, but could see it working that way in the right circumstances.
