My fan page is one of my greatest assets for my business!!!

It wasn't, at first, but I did a giveaway and got a lot more followers and now I have more traffic from there than anywhere else! Some people choose twitter, some blog all the time, but facebook is my favorite means of advertising. You have to find something you like to do. I have a twitter account, but it's not really my favorite thing. But I really like connecting with people on FB. It's fun!
