I should also note that I'm happily using AsciiDoc with Hugo instead of MarkDown so I was hoping it was available here.
I think that's a general misunderstanding and that often "simpler is better" should apply (e.g. the Unix philosophy about tools). In this case, I think that parsing either format is equally complex and that MarkDown's complexity is greater than AsciiDocs when considering the lack of compatibility between extended features (e.g. I found subtle rendering differences between Github and Gitlab which were our public and private repos at my last position.
I think the real fallacy here is that it will cost too much to switch. It really only took a couple of days for muscle memory to adapt from Markdown to AsciiDoc and so I'd challenge HN readers to give AsciiDoc a one-week trial.
SidePage is bootstrapped with Serverless SaaS, a starter kit I made (https://serverless.page), and I forgot to change the name inside the email template.
Should be fixed now.
