You know you're not supposed to write the symbols in and around the tags by hand, right?
I frequently travel for days without my laptop, and need to maybe add an FAQ entry or clarify a feature. Doing that with Plim is a breeze.
I really like low-symbol languages for day to day stuff. It's why, as much as I deeply despise it, I still often use yaml.
If I need safety in some form, yeah - lots of symbols allow a lot more information density, and that helps resist misunderstandings. That's hardly necessary in a personal blog though.
