This article might be of interest in this thread, as it's about an author's social media presence.

Clicking on the link to the study by McKinsey Consulting shows a graph that charts how effective different channels are in acquiring customers. Twitter and Facebook do poorly.
I'm curious if there are any updated charts. Looks like that data was from 2012 and, while social media was big, it has significantly grown over the last 2-3 years. I have heard the same thing on email, though, repeatedly - it attracts more customers than social media does. Unfortunate. That means yet another thing for me to do. *sigh*
