I probably wouldn't go so far as to use `sidebar__post__title `, just `sidebar--title` and `post--title`. That way if you want to style a post title in the sidebar, it's clearly `.sidebar .post--title` using something like BEM solves a lot of problems. Silly collisions and searchability are my big takeaways.
