Birds of a feather flock together. That goes double for CEOs, for who else can understand what it’s like to be in the inner sanctum sanctorum but other CEOs? Forbes.com, one of the most popular destinations for C-level execs, this week expanded its CEO Network to include community-type features. The password-protected, invitation-only area of Forbes.com, which originally launched in 2002, now allows C-suite execs to share information, opinions and advice. It can be accessed from Forbes.com’s main navigation bar. EDS is the exclusive sponsor.
