I'm starting to believe that the only way I'm going to get more writing done is to just write and post as I did with Magician's Merger, which is itself an example why that method is not ideal. The plot is imbalanced, and it has several dangling threads and false starts.
On the other hand, trying to write in advance hasn't been getting me anywhere.
I'm kicking around the idea of just writing, calling it the alpha release, and warning people that they are reading at their own risk. It might not get finished. It might fall apart.
Perhaps I should take a page from Alexandra Erin's playbook and make it an open-ended Web serial with no ending promised. Lots of comic strips and television series do it.
