How does everyone feel about a JSON dicts separated by newlines format? (Like the JSON format that mongoimport can accept.)

Each sample of the type of data that I'm often dealing with tends to be nested in nature. Yes, I do have a script that can flatten out the nested dicts into a regular table, but that always results in a blowup into hundreds of columns.

Nice suggestion to share the raw data. I've never seen a researcher do that, I think many don't even save the raw data to disk before extracting what they want, but I always try to.
