Well, actually, if I don't include myself... the Real Agent Blogs Facebook Page has one Fan.
But as the old saying goes, "Every great Facebook Page starts with one Fan." I think Mark Zuckerberg said that, and 'old' being a relative term on Facebook.
Regardless, Facebook has become a phenomenon - and if you use it anyway, why not do some low-key, relationship marketing while you're there?
Facebook Pages for businesses are free, and come with many of the tools and features available with a traditional User Profile page - allowing you to post messages on a your Wall, add photos and video, etc. You can also install Apps like an RSS Feed Reader to pull-in your blog content.
Probably the best feature of all - is the ability to gain "Fans" - or, your new marketing street team. When someone on Facebook chooses to become your Fan, a link to your business page is included on their profile. (see left)
One Fan can provide a doorway to all their friends, and an endorsement without saying anything at all.
