Perhaps my single most favourite use of Twitter is asking for help, as selfish as that sounds. Last night, just hours before an assignment was due I needed a quote from an old edition of AdNews. I put out a call to my tweeps and Trevor Young saved my ass.

The fact that I can ask for a information, feedback or even an idea and receive multiple replies within minutes still amazes me. And this goes both ways, breaking down nearly all barriers between people. To me, this defines a community.

Imagine if a brand helped you, and likewise could ask for help and receive it.
