I am interested in the paper on the topic; if you drop what you have into a google doc and PM me the link I will add my thoughts. (I have similar troubles with old/new projects)
Sorry, my comment was ambiguous - I am not writing a paper on this subject but am struggling with finishing old projects on other topics, while being seduced by novelty. Writing up my thoughts on old/new projects would make the problem worse as this is well outside the field I need to make progress in to keep a desk over my head.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
