I'd like to see something like this used to display people's arguments in social media. Something like a mythical "machine learning argument analysis" process would look at comments and threads, then spit out something like Argdown. Then people could see what structure and flow different discussions have.

Could also be useful if there was such a mythical tool that could gently teach people to debate in a more logical manner. The user would write their comment, but before it is submitted, it is analyzed and helpful tips or edits shown to the user.

As an aside, I wonder how good grammar checkers have become since the Word 97 days? My grammar is utterly terrible and I wish I could get it proofread before I make comments.
