I wouldn’t know, that question is apples and oranges different.
Twitter is creating a syndicated public one-to-all feed system; Email is a syndicated private one-to-many feed system. The public/private difference cannot be discarded and makes your question unrelated to my statement.
I encourage you to pursue a top-level thread about your concern instead, so that it’s not disregarded as a reply to mine.
Email lists are not private if you choose to sign up for one and post to it, the same way Twitter is not private if you choose to sign up and post to it. Email lists are very similar to Usenet which was the precursor to all these social media sites.
Apples can be orange in certain breeds or lighting conditions, but that doesn’t make them oranges.
Twitter is not equal to an email list. They share certain aspects but they are significantly dissimilar in UI, approach, social perception (by participants and by others), and publication.
M Twitter has not replaced mailing lists, and mailing lists continue to operate effectively.
Twitter is an electronic billboard that anyone with an app can post content to, and everyone can easily see it and do the same. Mailing lists are a town hall meeting inside a building: you can see them if you like, but participation from bystanders is quite rare and is often frowned upon or openly prohibited by the meeting’s coordinators.
You’re acting like there’s some extremely clear difference, but there isn’t. The only real difference is that email has kind of a bad UX. The comparison is not apples and oranges, it is grapefruit and oranges.
