This question is more in response to the answer to my previous question

Seems like -[this is strikeout] would reasonably result in this is strikeout -- given that ![alt] is already used for images.

That way you could use strikeout in comments.

    It should be noted that being in markdown does not guarantee allowance in comments - comments only support a limitted form of markdown. To use your very own case, this isn't going to render as an image: !.

Why? Strikeout is already supported in the HTML, eg,

<s>not this again</s>


not this again

(yes, <strike> also works)

I don't see any real value in adding random new Markdown syntax when the HTML we all know and love works fine.

  • Good choice. To extend a bit on this: "adding random new Markdown syntax" implies that basic Markdown itself does not support the proposed syntax (while it does support the image syntax that was mentioned in the question). Making up a new syntax for strikethrough would probably not make a lot of people use it (many simply being oblivious about its existence), but meanwhile make it hard for third-parties to interpret the data dumps.

    Except it doesn't work in a comment. <strike>Example</strike> <s>Example</s>. Dec 7, 2010 at 14:07

I'm a fan of Trello solution: they use double tilde for strikeout text ~~like this~~, that appears rendered like this (they use the <del> HTML tag).

It's easy to remember, and resembles the ** we are already using for boldly emphasized text.
