Even with the prefix, it’s not really HN etiquette to post comments that are entirely or predominantly pasted. And I’m happy about that.
Even here, you’re “Abstract:” comment was just a wall of text that would have been easier to read on the other end of that URL and with little less convenience. There’s just no need for it to be pasted in as a comment as well, unless you had something substantial to add alongside it.
I wouldn’t generalise your preferences to HN etiquette.
I personally like having some context in the comments as I often check the comments before the link - that allows me to see what the community thinks of the content before I check it out for myself.
OK, thanks for letting me know! It's a bit tricky to upload ArXiv links, I have a sense that not a lot of people will actually click through to read the paper or that some people just won't bother to click an ArXiv link at all, so I think that was my reasoning for sticking the abstract in the comments. but you're right that it's a bit hard to read. thanks!
