Slate has a list of 50 companies using Facebook well. It isn’t about yelling “Be my fan!” (And any companies doing that should fire their PR/Marketing firm, because being a “FAN” is about want not begging).
One strategy is to use Facebook for contests. That drives traffic.
Another strategy is polls. There is nothing better than customer feedback.
Oh, wait, there is: Customer reviews, photos, and stories posted right to the fan page.
Target used its fan page to let customers determine the charity. If you have a corporate giving strategy, a fan page is a great place to let your customers (and the public) know about it and maybe engage about it. By engage, I mean, join in – dollar matching, blood drives, food collections, etc.
But using Facebook to collect your boring ass posts, blogs, and tweets isn’t a strategy. That’s aggregation of your content.
And for those that tweet to Facebook: you probably tell the same jokes at every cocktail party.
