Hi everyone -
We talk here a lot about the benefits of social networking for small businesses. Here's another website that might be of interest: yelp. Though there is certainly no shortage of competitors, Yelp is this far dominating the internet market for small businesses. It is basically a listing of all sorts of services that can be searched by the type of service or the location. In that sense, it is like the yellow pages.
What is more important is that it allows customers to leave positive or negative feedback. That feedback can be viewed by the general public and commented on/addressed by the business itself. If you have a free second, you may want to check out this website and see if you are listed. Its also a great idea to encourage others to view this site and leave positive feedback based on their experiences with you.
