Keeping track of story ideas

I've mentioned my poor memory skills on the blog before. Plus, I really prefer to work on one writing project from beginning (outlining) to end (final draft/POD file creation, depending on the project). So, no surprise, I have a method for keeping track of the random story ideas I have while at work.

First there's the slim moleskin notebook I carry in my bag. It's not just story ideas in there though, I take notes during writer's panels at conventions, on using the print-on-demand machine at my local library, while listening to the Writing Excuses podcast, interesting things from non-writing podcasts, good quotes from actual play gaming podcasts (I listen to a lot of podcasts at work okay?), and have, on occasion, hand written a scene from a current project (I was really frustrated with work that day). Every few months, I try to read through the whole notebook again, to refresh my memory.

More recently, I created a new list in my to-do app on my phone (I use Wunderlist), titled 'Story Ideas'. I initially populated it by going through that notebook and adding an item for everything I'd labeled 'story idea', thinking it'd be good to have it all centralized. The full list currently sits at 15 items long, one of which is the collection of writing prompts I think I should free-write off of one of these days. One of those items is definitely a novel, conceived as such from the start and so firmly in my mind that I noted it with one word (the main character's nickname, actually). The rest are between two or three words, with notes if necessary. But I think most of them will be short stories, which surprises the heck out of me – I thought my natural writing length was novellas. Up until I started writing short stories off the latest RPG campaign I'm playing.

So dear readers, what should I write next?
