Ironic, but the underpinning of Web 2.0 is something so old that we take it for granted.

Email is at the core of just about anything else that you do on the
Web: it is the primary notification mechanism for Facebook et al. when you make changes to your site. It is the way these social sites find your network of contacts, and the way that you keep your audience informed of what you are doing, too. You can have the best Web site going, but you need to remind people about what you have on it.

Ironically, that was the original reason that I started Web Informant lo' those many years ago.

Why bother with an email list when you can just send out a bunch of emails from your desktop? Several reasons: First, you get a more professional means of communication that can manage all the bounces and mistaken reply-to-everyone situations. Your desktop program isn't designed to send out a message to hundreds or thousands of recipients either, while the list servers are. You also don't have to reveal all your subscribers in the "To:" field, which I still see from certain PR people. (Hey, thanks for sending me your contact list! I will be sure to take note of whom you think are my colleagues.) Finally, a list server or list provider can manage unsubscribes automatically, as well as post your messages in an archive that is available online for anyone to review.
