With the evolution of Facebook and Twitter, isn't that (for the most part) all that you need? Facebook was designed originally to connect people with others that they know or have some sort of relationship with. That is the notion of friend-ing. Twitter is designed to connect to people that you don't know through trending topics. That is what the hashtag is all about. It became some effective that Facebook adopted it. I'm not saying not to use Pinterest or Instagram. I'm not saying that at all. I'm just asking the question, if one were to focus on generating a business, is Facebook and Twitter sufficient. Is there something that is being lost by not going to Reddit, LinkedIn, Pinterest, Instagram, and all the others? What do you recommend should be the focused social media sights (in general) if one were to do a good job representing their business?
