I hate the new UI but I have to use it daily to get the WYSIWYG interface. Otherwise I have to convert my google doc to markdown before pasting it in. But I only use it for posting and then go back to 'old'. Most of my browsing happens from Apollo (iOS indie dev reddit client). That said I'd put effort into writing my own google->markdown->reddit-poster-script in a heartbeat if it meant killing off "new" and going back to "old".
