I have a business FB but twitter for me actually works better and instagram, I just made both accounts for my business last week and so far I have 122 twitter followers and only 4 FB followers. I have always struggled getting FB fans even from my other successful ventures, I always have a better reach with twitter, I'm also hoping more costumers will come from twitter and instagram as well, I am still working on pinterest, it hasn't worked for me before but I will start to figure it out soon, since great images = sales.
