@koos that depends on your intent: What do you want to achieve with your blog posts? (Depending on your answer, I might be completely unable to give advice though)
@koos I usually blog technical stuff in a sort of post mortem format: What did I try to do, why did it go wrong, what is the technical lesson.
Examples: https://www.orkpiraten.de/blog/why-i-dont-identify-as-sysadmin-anymore and https://www.orkpiraten.de/blog/subsonic-with-caddy
@JollyOrc any standard structure or something you use?
@koos apart from that outline (aim, problem, solution) not really.
If you want your content to be found by search engines: Put yourself in the shoes of the folks who have the same problem, then include their most likely question into your post.
@JollyOrc yeah I'm not so worried about SEO. It's more about forcing myself to write down what I learn and having a way to share it with colleagues and friends.
@koos then do it in whatever format is most fun for you. That way it's less a chore :)
@JollyOrc :) When I write it's about design: technical stuff, process and purpose. Currently I'm writing about color: quite technical, but I like to make it as human and light as possible.
