Never have your content only on someone else's site.
I usually write every comment / opinion in Obsidian if it's either long or seems like something I need to explain multiple times.
That way I can just copy-paste the same comment again, read through and edit either the original or the pasted version to fit the situation and I save a lot of time and research =)
