> QA / PM / whoever is on your "team" can ask quick, simple questions, that are either too small for an e-mail, or would seriously slow them down if they had to write the e-mail, wait for a developer to check e-mail, write a response, etc. Again, in my experience, developers routinely underestimate how much inefficiency having QA / PM / whatever blocked while they wait for information from a developer generates.

It should slow them down. If they are blocked multiple times a day, it isn't the communication method that is the problem, it is the process. Interrupting developers multiple times a day is not the solution.
