I personally consider myself a dino when it comes to all the technology out there. with that said, I don't have a facebook. Lot of people swear by it, but it's all on you. I have a twitter and just recently began a blog, which are keeping me busy enough as it is. So, I recomend for you to take baby steps and don't overwhelm yourself. Learn one social media at a time and invest the most time on your store and products. Hope this helps:)
