Stand out from a crowded job market by writing technical blog posts. This is super valuable advice I wish I'd known much earlier. Now I'm in a position to make hiring decisions, developers which can prove their mastery and passion through their writing stand head-and-shoulders above other candidates. Perhaps most importantly, through writing, they demonstrate a clarity of thought and give an insight into their personality which allows them to effectively shortcut a major part of (at least my) interview process.
