My business isn't very local. Most of my clients are out-of-state. I use listservs, Yahoo Groups, LinkedIN, ZeroDegrees, and conferences like ISPCON and ITexpo to find prospects, interact, learn, and talk to clients. I also use this blog. Locally, I attend TBTF events, Business Luncheons, Lunch-n-Learns, and Chamber events. What are you using?
A new website called MerchantCircle.com allows you to endorse other local businesses - and to connect with local customers.
