I have a Facebook fan page & Twitter account. I have my Facebook posts linked to my Twitter account. My Facebook "fan"s are totally different people than my Twitter followers. I will post to Facebook 5-6 posts per day to my target market. As for Twitter, I will post numerous articles (I don't count), re-tweet others, have exchange with people and more diverse subjects but always keep my market in mind. They are both ways to create visibility for yourself but very different ways of interacting and different audience. It's much harder to get Facebook fans than Twitter followers. To me, Twitter amplifies your messages much more than Facebook...but that's just me

Ok, so I admit it...I'm totally hooked on Twitter!!
