There was another post on HN a few days ago which likened publishing blogposts to increasing your luck surface area and I very much relate.
When I get hit with writer’s block and can’t seem to come up with my own work - which can be months at a time - I end up reverting to something like email interviews to highlight other peoples’ work and still have content for my blog.[0] Similarly, guest posts (that you seek out, don’t let random writers write guest posts aka insert links on your blog) can keep your blog “alive” through periods where it otherwise would have died.
