markdown makes sense for things like documentation, but with these sites like gamersnexus i think there are some issues

1) how do you migrate all the existing content from joomla (which they do want to migrate) - would it be in some terrible html only format? would it be a mix of html and markdown?

2) how do want to use markdown for articles like https://gamersnexus.net/features/inside-collapse-artesian-bu... ? it would be highly customized markdown anyway, and the more markdown additions are, the less markdown makes sense anyways since portability becomes an issue

I think their current approach is fine - render once and cache is pretty normal. With that being said less is more and I hope they did not implement a lot of plugins or custom code that would require maintenance every other php/drupal upgrade.

What I would like to see instead is using svg graphs with high accessibility instead of just pictures.
