Listener Sad because station is not on Twitter

Here's a Twitter post from @CharloteAnn about KRTU, a public station in San Antonio:

CharlotteAnne Oh sweet @krtu, why in the world are you not on Twitter so I can <3 you for playing so many wonderful jazz versions of My Funny Valentine?

Radio stations, both streaming and terrestrial, absolutely should be on Twitter - actively. It's the perfect place to connect with your audience.
