If you work at a big agency, it seems like once a week that somebody sends out an email about farewell drinks and plans to join the freelance army.

There are lots of reasons for the explosion of advertising freelancers in recent years. From an agency perspective, more project work versus AOR assignments means that agencies are less likely to take on permanent staff. From the freelancer side, many people like the freedom and flexibility that freelancing provides. The money is pretty good too.
