First and foremost, thanks for giving this a read over. I know it's a personal question, but I feel like it's data that can really help me, and others out.
A little about me. I'm a Lead (senior) level developer working in the advertisement industry and my yearly salary is 80k. I work in Washington State and always felt that this salary is a bit low considering I work near Microsoft and Google whose senior level engineers make 100-110k. This December, I'm hoping to be moved up Technical Director (basically in charge of the lead developers). The salary will be around 100k, which I still feel is a bit low. Perhaps better knowing the distribution of salaries, I can better judge where I'm at and help me negotiate a better salary in the future (or be content with what I have).
I'll also share this information after a couple of days and give some nice charts!
Once again, thanks for helping me out!
