If you're in some sort of "web developer" ghetto, maybe that's possible. If you have a software engineering job title, you can get over $100k entry level in Seattle, even if your actual job duties involve web development. This is total comp, not base.
I don't think that MSFT figure is accurate at all anymore. From what I understand from some of my peers, they start somewhere around $85-90k now, base salary. Glassdoor more or less agrees, for whatever they are worth.
