Text message marketing is not a very profitable. People actually find receiving these messages frustrating. Most people treat text messaging like a phone call. You love it when your friend calls you, but when that telemarketer calls, it makes you very upset.
Social media is basically free marketing. How can you not want to take advantage of it? The good news at least about some of the sites is you can control who or what is posted in the public view. The world is living on the Internet now; it would be a good idea to get involved in it quickly.
