Good luck getting traction. The web is littered with the corpses of "comment on any website" apps. The problem is that there are too many websites and too many incompatible "comment on any website" standards for any one of them to emerge as a clear leader.

P.S. You list non-tracking as a differentiating feature, but how do you silence speech you don't like without tracking users?

Listen to Walter, you don't want to be an island of comments in this case. Following annotation standards will allow this content to be gathered and reused elsewhere, for things like fact extraction, sentiment analysis, meta-discussion, +++, it will also allow others to immortalise your content if you happen to fail.

On the other hand, maybe that's exactly what you don't want. My personal pet peeve is comments on scientific papers, where openness of this content is not only desired, it's crucial. Your situation might be different.

'The web is littered with the corpses of "comment on any website" apps.'

There is one "comment on any website" tool that has existed from the beginnings of the web and still thrives. The way it works is, you put the comments on your own website.

Do you mean, post comments you have about another website on your own site? Definitely works, although obviously harder for others to discover your comments compared to a single commenting tool which everyone used. Although I'm sceptical such a tool will ever exist.
