The limit I see with this is that it does not provide an obvious means of referencing the various links in other posts. Although it is possible to use fragmentions to link to a particular part of the text, mentions are listed against the whole text itself. The alternative might be Hypothesis, but then you lose reference to webmentions.
My solution has been to record each link as its own bookmark and then collate these. Therefore, I am able to easily link to a specific URL, while also providing a summary.
I have thought about removing the posts from my URL, but for now I just let it be.
