Just manages to whittle down the size of my homepage from about 450KB to around 85KB just by tweaking the remote font calls and downloading & cleaving the forkawesome woff2 and css files to contain only what I use.. also properly scaling profile and footer images.. could minify the css for another 5KB but given hugo doesn't want to apply minification during processing it isn't really worth it.
I need to go through and properly scale a whole lot of images for other pages but not a bad start.
