I thought it was implied that I wanted my blog topics to also be helpful. However, blogging takes a lot of work and if people don't find my blogging topics to have a clear theme - it loses clarity and therefore risks not helping anyone.
I choose to focus on accessibility even though I have plenty of technical interests. This is the one topic I am most passionate about and have the most capacity to help others with. It also supports my long-term goals of being recognized as a subject matter expert on this topic. It's not mutually exclusive, in my opinion.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
