I can't disagree with this, since I landed my present job through climbto350.com... (mine was right place, right time, right qualifications).

However it's worth noting that the competition on this (and many other aviation job search websites) is fierce.

When my current position was advertised, my company posted it for 4 days before they took down the ad. In that 4 days, they received over 1200 resumes from every state in the US and 7 other countries (including as far away as Israel and Japan)...

Networking is definitely the best option, but use all available resources! Good luck!
