Run a User Survey
It'd be nice to run a survey to better understand what our users want from the library. 

We can ask things like

* What version of pandas are you using?
* Is pandas stable enough?
* What APIs are you using (e.g. which `read_` methods)?
* What features would you like (additional readers, etc.)?

I plan to put together a form sometime in the next couple weeks. If there are questions you'd like to see included, please post them here.

See https://github.com/dask/dask/issues/4748 and https://t.co/OGrIjTLC2G for inspiration.
