I recommend being cautions about adopting Confluence as a critical part of your engineering and your business.

I have been using Confluence for almost twenty years. I have used Confluence on a variety of projects and I have my own Confluence Cloud account.

Until the last few years I was an Atlassian fan-boy and regularly recommended Confluence. Those days are over.

I have so much information on Confluence that there is no easy way to leave Confluence for another platform. This means that I am in a marriage with Atlassian Confluence and this marriage has become difficult.

Atlassian released a new editor for their Cloud version of Confluence. This editor was missing some critical features that I count on my my software business and my personal life. The feature that they left out was the ability to upload a document and create a link.

For example, I have invoices that I submit to consulting clients. The Confluence page that keeps track of my invoices might have a line like:

Client X invoice Aug 2020 is here

In this case, the word "here" is a link to the uploaded document. Clicking on the document would display the PDF.

Atlassian did not support this feature in their new editor. Since I have relied on Confluence to keep track of a wide variety of documents, this was a huge problem. Only after a great deal of uproar in the user base did Atlassian provide access to the "legacy" editor which has this critical feature that many long time Confluence users need.

I wrote the co-CEOs of Atlassian twice and posted numerous times on the discussion blogs. Other users did similar things.

To this day, after something like two years, the features from the legacy editor are not included in the new Confluence Cloud editor. The Atlassian staff has not been responsive. Atlassian has started to remind me of Microsoft rather than the start-up company they were years ago.

As I mentioned, I have so much information in Confluence that there is no way can reasonably move away from the platform. So I would carefully consider whether you want to put critical information on a platform that may not be responsive to your needs.
