A great post you made there! Hope you progressing with your project and get some enthusiastic followers and contributors already. You are on a mission for sure! Keep the passion going :)

The code you have in your post seems to be HTML. PeakD supports both HTML and Markdown. I think hive.blog as well. But, it doesn't auto recognise the language, so you need to flip it yourself. Both interfaces have a clickable link in the post edit mode. I always use markdown, since this is quite simple and all main interfaces do support that.
