I used to blog almost daily. My motives were selfish - writing down things I learned helped solidify and process them in my mind. Over time those things helped other people who came across my posts as well. Even though I think I've gained some good experience in a few areas, it feels weird for me to write anything and position myself as an expert, even if I feel that my contributions and knowledge are valuable. I second guess myself and wonder all the stuff I might be missing, or things I don't know, all the things people could find wrong in my suggestions. So even when I feel like I know what I'm talking about, if I do write it down in a post it is often from the perspective of a learner sharing an experience about what they're learning, not an expert going "Here's how you should do this." or "Here's how this works." And with things that I know I know a lot about, they just feel so trivial - "Everyone must know this, it's not interesting at all." So I often don't bother writing it.
