I initially loved Dropbox Paper.

However, being so easy to manipulate it has become a place of braindumping. I begged my boss to separate his personal notes vs. company documents. It has gone out of hand. Tons of unattended documents that people have forgotten about.

Creating new documents and editing them has become so cheap (congrats to paper devs for managing that) that its backfiring in our case.

As for team conferencing, we used many many different tools. Recently we started using zoom.us and the quality is amazing. Much higher framerate and resolution with a better CPU usage.
