Out of post ideas. Got any ideas you'd like me to take on? Stick 'em in the comments.
Keep it kind of brief, though, like: "The something-or-other crisis," or: "Science vs. whatever," or like that. None of this really detailed "Oooh! I want you to write a story about a unicorn stalking a wounded, pain-enraged killer bear in an attempt to save the nearby village of Elf Hollow, all written from the standpoint of a circling bluebird!" No thanks! You can write that one yourself!
What I'm getting at is, I prefer you leave it open-ended.
Also: it goes without saying, if your idea is used I will thank you in the comments queue, but not within the text of the post itself. You wouldn't want that anyway! It would mar the final product, putting in all these footnotes and claimers.
