I suppose it is all how you define "flirting." To me there is an objective. One does not flirt with friends, if they are being a true friend. To me, flirting was like an invitation: I like you. Let's spend more time together and see how that goes. I can have a laugh and enjoy an evening out without it considered flirting. But that is my understanding of the word. :-)
And I won't be getting a smart phone, if I can help it. I am at the age where it might be okay to get a "granny" flip phone that just calls and texts. That's all I need, and if I didn't live in the country I wouldn't even bother.
But the skills learned in that context aren't flirt dependent, they are all relationship applicable. It is just a testing and practice ground with additional incentive.
I wouldn't get a smartphone if I could avoid it either :)
