It depends on your objective -- sounds like squidoo will help you with your SEO efforts, where facebook is a place to build a community, but will require a time commitment to keep it relevant and increase your fans.
I know that we are starting to offer specials such as happy hour for our hotel bar/restaurant through updated tweets such as "twitter tuesdays at the Commodore Grill Restaurant, come between 5-7pm for $5 martinis"
no, though my goal is to promote my new line via twitter and my blog once it's complete. i do however follow someone who uses twitter exclusively to promote their etsy shop, and it seems to work well for her. @adnagam
It should provide information that you cannot find on the regular site and allow the friends to feel like they are part of the "inner circle" and part of a special community.
