Do not feel guilty about asking for flight following or any other ATC
service. If the controller is unable to provide you with the service
because of a high workload, then he will tell you he is "unable flight
following at this time."

Part of good CRM is taking advantage of EVERY AVAILABLE RESOURCE to
reduce risk and contribute to safety. VFR flight following, be it
terminal or center radar is just one more resource. Use it.

Point taken, but I know that ATC's first priority is to keep IFR
flights safe, and in busy airspace I'd not want to take any risk of
distracting them from that job. If it's quiet I might ask for flight
following, or if I felt that I were in a risky situation myself (lots
of traffic nearby).
