I ditched Docker for Podman

To bikeshed a little, "Why I Ditched Docker for Podman, And Why You Should Too" would be better than the current headline of "Why I Ditched Docker for Podman (And You Should Too)": the "you should too" part is after all the main message of the article, not a side-point.

"You should too" is the part that annoys me. I use podman but if you are happy with docker, fill your boots.

I'm a fan of grammatical radicalism, the parens are appropriate if they're meant to convey a certain tone/voice in the writing, like a quick added-in-fragment after you're done saying the original title (as if you were giving a presentation).

It sounds as if what you want there is an em-dash.

The HN title was altered from the exact title to a modified title that changes the meaning. I don't understand why.

Also valid--but I think both work.
