I use it regularly. It's not so much about sharing,which is easy and works well, but about getting data into Domo. Pain point to format data and schedule exports, update them, set up new exports, etc.
I've been talking to the product team a lot about related feedback lately. If you want to share your thoughts, I'd love to take them down, and make sure they get to the right folks.
Also, have you seen the new export API? It could solve part of the problem you mention. adam.chavez at domo
