I would say the answer is yes, provided you're ready and willing to be able to capture that information, sort through it, and begin to work with it, and that you're also ready and willing to be engaged in conversations with people. Twitter and Facebook can be remarkable push technologies, but they can also be remarkable from the perspective of hearing back and forth and opening certain kinds of discussion. Twitter being Twitter, you only get 140 characters, so it's not necessarily going to be deep, but that's okay, because what it can do is you can use it as a really terrific pointing tool to focus people on a more discursive kind of content that might be housed on a website somewhere, or to point people to an event they can attend, highlight other kinds of resources that you are examining, point people to the ParlVU website, to let them know that these kinds of conversations are happening. So provided you understand your strategy in terms of the kinds of things you want to do for people and what kinds of conversations you want to lead, I think they can be remarkably helpful for you.
