How many of you have received contracting or job leads purely from blogs/articles you've written? What sort of posts were they, and for what sort of client? Are they heavily domain-specific, or more broad in nature? How valuable is this as a source of leads vs. other means (e.g. in-person networking, referrals by past clients, etc.). Do you have other advice here?
My own short story stolen from a co-worker: they had written an article on basic vagrant setup of popular open-source online school software (think edX, Canvas, etc.). This had eventually resulted in a contact by an agency doing work on that platform, who needed contract hours. I was always struck by how relatively "cheap" an ad this article was, and liked that it did provide value in the dev community.
