wget -mk --no-check-certificate https://singpolyma.net/
And it seems to be pulling down all the pages and resources and blog posts, but it's missing a large number of the /actionstream/* URIs. It gets some of them, and each of these pages has prev/next links which should mean it can get all of them, but it doesn't. No errors in the output.
I tried changing to start at
https://singpolyma.net/actionstream/reply-httpidenti-canotice72478545-russellmcormond-thats/ but that didn't work either, it in fact got even less of the /actionstream/* items.
There must be some switch that I'm missing. I thought the -l inf from -m would do it.
