> my impression of email is that it's very hard to use for communication because it's too formal, so it's hard for average people to communicate with
Once it goes external sure, but email is ubiquitous in most companies on Earth and ranges from highly formal to casual shitposting internally.
Many have tried to replace it unsuccessfully despite all it's setup, usability and security flaws, there's a reason for that.
For me: I love the balance between meaningful and impermanence, that I can delete the cruft and organise the important stuff to keep for later, you can filter everything into folders that hits your inbox with a few a clicks, that you can have multiple and shared inboxes for appropriate workgroups. When I worked at _bigcorp_ it was common for a new hire to ask a question and someone would respond in a minute forwarding an email from 7 years ago explaining how to fix the problem.
