Terminology within the /e/-environment is confusing ("/e/identifier", "/e/cloud", "/e/account" "/e/drive")

Summary

Please consider this as a feature proposal.

I am observing the the usage of the terms "/e/identifier", "/e/cloud", "/e/account" "/e/drive", /e/email could lead to confusion and should be revised carefully before v1.0. I am referring to the OS itself as well as to the website and the documentation.

Example: When singing up for an /e/ account, there is the term /e/account used. But the link name for the respective documentation page refers to “ecloud-account”: https://doc.e.foundation/create-an-ecloud-account

Another thing that I consider confusing: Photos and documents are stored on /e/drive, which is part of the /e/cloud. But: Notes and Tasks (as long as I use the stock apps) are stored in the /e/cloud but not in /e/drive, right? And the /e/account’s main feature is the /e/cloud. And the /e/email address is the identifier for the /e/cloud respectively the /e/account. But it is an email address anyway right. Am I mistaken? (P.S. I wouldn’t dare to make any attempt explaining this to my mum…)
