Ok, so you are looking for lead-gen in the biggies–Linkedin, Facebook and Twitter. Maybe even in Google+ groups too. But there are SO many social networking sites out there now and you have only so much time.
There’s a catch–it can be easy to get lost in the chatter on the big sites. What about trying some brand new networking sites that are rapidly gaining traction? They can give you a distinct advantage to making new connections and might be a better use of your time.
