To Facebook or Not To Facebook?

To Facebook or Not to Facebook? That is the question I've been asking myself since I started my shop on Etsy. Just about everyone has one. I feel like I should have one. But I'm not sure. I don't (really) know how it works, though I'm sure I'd be able to figure it out. I'm using Twitter, which I never thought I'd use, though I'm still trying to understand all those hashtags and retweets, etc. Like Twitter, I don't know if Facebook would be helpful to me or not. How do people find you on Facebook any easier than they would on Etsy? If you get "like"d on someone else's page, then I suppose all the people looking at their page will see yours? But what makes them click?

I suppose what I'm going to have to do is go in, sign up, and see what I can figure out. It's helpful that my teams have posted a lot of information about it, and have given their page links so I've got something to look at. So, readers, do you have a Facebook? Do you find it useful? is there some magic formula to it? I'd like to know!
