Not meaning to toot my own horn, but just to give a testimonial for blogging: At the client I'm working for right now initial contact was at C-level. (At a software company which you've heard of.) That isn't the first time that happened, either -- if people are really interested in what you have to say, recruiters, resumes, and the HR department are not merely bypassed, they're never even thought of.
This is obvious and old hat for the more experienced corporate drones here, but it's important for all the newbies to understand that [all, but especially HR] processes and policies are made to be broken, and they are often so dysfunctional in large corporations that if someone at an appropriate level wants something done, it will be done.
(My personal experience suggests that managers and below have 0 power, and only directors+ start being able to work the informal network.)
Is it not only what you say but what you release? Are companies interested in the minimum viable products (Show HN:...) that bloggers and hackers release? I have been looking for a job for months now and I am wondering if this could be a point of entry.
