There's always space for email. My private phone conversations might be useful and/or interesting to random people and somebody out there might have some helpful insight, but seriously... They're my private phone conversations.

Maybe I'm old school, but for me, there actually is something appealing about expressing a thought in more than 140 characters and specifically to a person of my choosing. I'm Web 1.0 like that.

Exactly right. Email is private and will never go away. But twitter is useful. They're just different.

So different, that we created posterous to bridge the gap. =)

Translation: Apples vs. Oranges. Fight!

foulmouthboy is right: There may be some overlap between these two communication mediums but they have two different purposes.

Maybe e-mail clients should have a button "post to blog" for instances where people want to share their emails immediately to others.

Use a Send button. http://posterous.com/

I set up an email address that would automatically post to my blog. That way, I can edit posts in an editor I like rather than a horrible textarea. I've had this feature since, oh, 2001 I think.

Email has it's share of problems, but it is a necessary tool. Businesses are utilizing Twitter and other media more and more, my office has only two people I can think of who aren't on twitter. It is used for inter-office communication etc.

However, email is the incumbent technology so it takes a major paradigm shift to unseat it. Something I haven't seen any new technology come close to.

I believe Twitter is a solution to the too much email issue, especially when they allow for groups. It forces people to get their point across in 140 characters. Why go on and on?

Mailing lists are there for a reason.
