I think we need to standardize the sarcasm tag on the Internet.
Not one of those RFC that no one implements, but something concrete, perhaps baked into the HTML standard. (If the W3C include DRM, they can include sarcasm).
Or maybe something like ISO, but people ignore them too.

There was recently a NYT article on trying to get a ballet shoe emoji (high heel shoes & sexism related) into Unicode.
Sarcasm should be in Unicode!

>Sarcasm, Inc. was formed in 2006 to pursue this idea, and with a great deal of effort and undying support from family and friends, the punctuation mark for sarcasm came to life.
This is why America is the greatest country in the world!
Sarcasm Inc even has (sarcastic?) shareholders and apps!
And we all know what is meant by "X, er, that is, Y"; it's even used intentionally in verbal language.
I think it's more that effective sarcasm in text requires the audience to know the viewpoint of the author. So, sarcasm among friends over email can work. Sarcasm in the concluding paragraph of an article can work.
Sarcasm between strangers in comment sections, less so.
