In the 21st century support comes in many forms. Support is a kind word of encouragement, a thank you, or yes, even a "like" on Facebook. All forms of support can be taken to the next level. For example this is precisely why the "share" was created. The ultimate form of social media support.
However, I will contend the best kind of support still comes through human to human interaction, conversations, and interest. Yes - engagement, so if you truly want to maximize your support for somebody or something, then show interest and inquire more about it. This form of support trumps every other by a mile. Don't believe me, just think about your own life. Which means the most to you?
Support your customers. Support your friends. Support your family. Support makes a world of difference.
