Belonging to several networking organizations got to be too much at one point and I had to scale back. The group I opted to stick with was the SBCN, because to me it offered the most value. The events are monthly (plus special events), which is easy to make time for. And if you make a commitment to attend as I have, it doesn't take long to start to build familiarity with the connections you've made. Plus new faces are sure to appear at almost every meeting, so it's easy to make new ones. Linda and Dave do a great job keeping the theme fresh and interesting, and the membership fee is trivial. To me, the SBCN is the essential networking group to belong to.
