response-able

Twitter was originally invented as a broadcast medium without all the @ response stuff. Its users had to invent the response functionality for them (see 4:00), Evan says so himself here.

 

That W+K Old Spice stuff was a "response strategy", says so here.

 

 

Being able to respond is the basics of communication, conversation and dialogue. Without it you're just monologue broadcasting.

 

So get response-able.
