I like it! may be add an option for users to group themselves by the type of work, i.e. coders with coders, writers with writers, let them optionally choose the kind of co-workers they want (or default to a random mix of strangers in "cofeeshop" mode)

and also let users work together on shared tasks, such as leetcode prep, school homework, startup or open-source project, or anything which requires collaboration.

Also you could provide "virtual PM" as a service to tech companies to manage their sprints.
