I've had people tell me its good to link these two and others (webinars and conferences) say that it isnt necessarily good because if you post heavily in your facebook fan page you end up spamming your twitter followers. That and i've noticed all they get is a condensed title and a link.
so what is folks opinions? good to have twitter auto update and tweet whenever you make a post on your fanpage? or better to manually send out those tweets about your fanpage updates yourself? Albeit time consuming
