re: Which Social Network Makes The Most Business Sense?
To add to this information, it's important to make a distinction between building awareness with people who don't know you and your company yet, and staying top of mind with those who do know you and may already be in your network. That will help you determine which social sites to use and your actions therein. For example, you may be using Facebook to connect with your existing customers, but it may not be as effective for finding new ones (unless of course your information is being shared heavily -- unlikely for many small businesses). For that, social media takes on more of a PR play. In other words, start communicating on sites where these new customers may be, i.e., related blogs, discussion boards, etc. In other words, look for "site swag" or free social activities you can participate in at sites where your audience is already hanging out. Take for example, The Knot, for brides to be.
