Will RSS ever replace email?

In short, answer is no.

RSS will never totally replace email because they each do totally different things.

RSS was designed for a totally different purpose than email, and technologically speaking, it would be impossible for RSS to do everything email can.

Consider this analogy: RSS and Email are like TV and telephone.

If you want to reach a broad audience of spectators, you use TV or RSS. Consumers like TV because they hold remote and can change channel at will. They have total control. Likewise they can an RSS feed at any time if they so choose, and instantly source of information is totally gone, never to return against person's will.

Most people when sending email send using to line, some even venture to cc line (carbon copy) but very few venture into realms of Bcc line (blind carbon copy).

The answer is usually because they are blissfully unaware of existence of Bcc line. Most email clients including Outlook Express and IncrediMail do not show Bcc line on default new email form when composing an email.

To Use Bcc line you must normally first enable it. These screen shots show how to enable Bcc in Outlook Express . The process for Incredimail is similar.

What is Bcc Line and why Use it?

The Bcc line (blind copy)is used to send email to someone without other recipients of email being aware that it was sent to those recipients. It is effectively a way of hiding email recipients from each other. Its main use is when sending email to mailing lists ( email groups).
