I've been using
<s> to put
strikeout in posts -- is there a Markdown way of doing it?
It seems like
-[Text here] would make sense, hehe :)
Yes. No. Maybe so.
This means that comments may not include strikeouts.
Though a strike-through syntax wasn't available in the original
markdown, as of today (2015), many implementations have unofficially settled on the ~(tilde) character which is supported on Reddit and as someone here mentioned, on Bitbucket too.
Let's hope Stack Overflow also adds this syntax to its Markdown implementation soon!
Why is the selected answer such a wrong and imprecise one ? !
Well, probably because people answer in comments rather than in... an answer.
While markdown technically doesn't support strikethrough ATM, several comments pointed out that using strikethrough in comments is possible.
Not handy, since ~ isn't supported yet, but actually possible (using unicode characters)
So, to striketrough text in questions, use the <\s> or <\del> tags
striked out using <\s> tag
striked out using <\del> tag
For comments, use external converters or tools, like those websites (credits go to respective commenters)
