If you are totally addicted to Facebook and spending far too much time lobbing virtual spaghetti bolognese at people, or sending vampires to bite friends, Web Worker Daily’s 12 Ways to Use Facebook Professionally should get you back on the straight and narrow. Tips include looking for old co-workers and current connections, adding friends selectively, adding applications selectively and joining groups that are related to your business interests.
