I really enjoyed "What posts are you planning on writing?"
This is the lazy version, for people who want a post to exist but want someone else to write it. Given that we're all stuck inside anyway, I'm hoping we can use this opportunity to get a lot of writing done (like Isaac Newton!)
So: What are some unwritten posts that you think ought to exist?
If you want something to exist badly enough that you'd pay for it, consider sharing that information! There's nothing wrong with offering money; some really good work has come from small-scale contracting of this kind.
