Connecting people online has become big business. Companies, including some credit unions, have captured the popular imagination by allowing users to write their own opinions, film their own antics, or leave very public comments on the Internet. This new trend, called “social media,” has become a powerful marketing tool. Used correctly, it can help attract young adults to credit unions and endear existing members to your institution. Used incorrectly, it can distract from more effective channels and give the illusion that your credit union is progressive.
