i'm interested to hear you experiences. Most companies I know (circleci included) are dying for skilled devs, though there's no shortage of not-great devs.
A very small percentage might be open to remote workers, but unless you live in or around these "hot spots" you're going to have a more difficult time finding work, not to mention a comparatively lower compensation.
(Interested applicants will read your blog to learn about you, but surely more prominent placement would generate more flow. Especially since your potential customers are your most likely employees.)
