A placeholder was added to the TextArea in the "connect with me" page.
Fixes #45

Hey @thomaslian,
Thanks a lot. I really liked your idea of using labels. Could you change the placeholder to a label because I feel it makes more sense? In the case of placeholders, after users fill up a social field, the placeholder is gone and they can get confused on which one to edit.

@rishavanand I totally agree, will make a new PR soon! :)
