Social networks can also be used to keep tabs on your vendors. Brandt, who takes great care of his LinkedIn "Rolodex", caught a vendor off guard when he asked them who his new sales person was after the last one left. Brandt noted the departure through a change in the person's LinkedIn status. The vendor, it seemed, did not know the guy had left.
You don't have to be on a social network 24 hours a day to enjoy the benefits. Keeping your profile up to date on LinkedIn, staying in touch with former colleagues on Facebook and jumping into the occasional conversation on Twitter is enough to build your social network persona and might find you that perfect hire for a job opening or provide the answer to a vexing question.
