Social media has come a long way with helping people find like minded individuals. Using hashtags and locations can help you find any niche, person, or business you are looking for. Search for your own business.. See what people are saying about you. If it's good, why not share it. If it's bad, try to make it right. Reaching out to a client or customer who had a poor experience can really make a difference.
