Social Media Profile Links as a field type for Drupal 7 content

What we're looking for is a way to automatically display links on a Drupal site to people's profiles on known social media sites in the way they expect, e.g. @mlncn for Twitter, +ben.agaric for Google Plus, and whatever the heck for Facebook. Icons a plus.

Evaluated https://www.drupal.org/project/social_profile_field and was not impressed at all; both the inputter's user interface and the display are sorely lacking.

Social Media Links for nodes as Fields

Lot of answers involving formatters, including (probably) https://github.com/LondonITGuys/socialmedia_link_formatter

(and someone there liked Social profile field)

Not so helpful Stack Overflow response:
http://drupal.stackexchange.com/questions/111974/social-links-for-each-user

And http://stackoverflow.com/questions/8028834/drupal-custom-external-links-in-user-profile

which had the cool suggestion of the Follow module https://www.drupal.org/project/follow
this is clearly the leader in this field.
