One other thing we've noticed is how slow Confluence and Jira are together. It's fascinating that stitching these products together under one Atlassian service (through acquisitions) hasn't served to provide a good or modern user experience.

We built our "define" feature to allow for spec'ing, and docs. And let's not forget how frustrating markdown is in confluence. We're working to really service markdown well in our text editor, and should have it released soon.
