Jennifer or Jen?

Jennifer or Jen? For online daters “Jen” would be a more appropriate choice.  Statistics from an online dating site called Badoo.com show that online daters prefer a nickname over the longer- original name.  The reason for this preference is that a nickname gives the daters a warmer feel to the person with the shorter name.  Tests ran in the US, Canada, the UK, Brazil, France, Spain, Italy and Germany all show the same results. A shorter name simply gives out a friendlier message, rather than a whole- longer name which researchers say would intimidate the dater.  The same results are shown for both genders.
