I try to remember that while social media is very “what have you done for me lately,” it also means when you finally do come back to it, you can pick up the buzz again relatively quickly. Those who defriend, ignore and stop RTing you if I'm away for a while tend to fall off my radar. Those who maintain contact over time, breaks expected, are the ones with whom the more superficial social media connections develop into deeper working relationships.

Great article, btw. I was nodding my head in agreement the whole way.
