I'm guessing that your intention was to show us https://bbs.archlinux.org/viewtopic.php?pid=1149530#p1149530 ? It would be better to submit the direct link to the post than to make people scroll through the whole page in order to guess which post you meant.
That is my intention yes, and I could swear that I did include the specific element on the link. But I guess either it was automatically removed or I somehow copied it wrong?
I got the link from Arch's wiki[1] (it's in the note at the end of the summary), all I did was right-click > Copy Link.
The page provides a "canonical" link in its markup, and HN takes that and replaces what you submitted. I believe you can change it back, for a certain amount of time?
