Say the page is “Hello world!” (CID: `QmXgBq2xJKMqVo8jZdziyudNmnbiwjbpAycy5RbfDBoJRM`), then the comments can “point to” this CID `QmXgB…` and so on. The problem to me is not necessarily the direction of the graph but the existence of this graph at all. IPFS seems to have no method of creating “references” to other hashes, but if it did then I can see comments working unless I’m missing something.
Yes that's exactly the problem: comments can include a reference to the page (via its URL); they can also reference any comments they're replying too (via their URL). Those URLs are the 'arrows' that I drew.

Such references would be arrows pointing the other way.
