the rss feed includes some garbage on the link to the comments. it seems it adds `item` before the `/` which renders the url invalid. eg https://twostopbits.comitem/?id=61 but https://twostopbits.com/item?id=61 works fine
(= site-url* "https://twostopbits.com/")
"https://twostopbits.com/"
(= parent-url* site-url*)
"https://twostopbits.com/"
