In the context of this post, i.e. publishing a small personal blog, simplicity works well.
Is it simple though? Copy & paste into a WYSIWYG editor is pretty error prone, and he's already talking about creating several shell scripts to keep things in sync. Seems a bit like re-inventing the wheel, no?
I find myself coming back to a metaphor that was in the comments here yesterday - yes, this is a beautiful, stylistic self portrait, but if your job is to paint the whole house this is a terrible way to do it.
