Menneisyys hits another homerun with another one of his insanely in depth articles.

Instant messaging is one of the key features of today’s communication. It’s much faster than e-mailing, much easier than picking up (and, probably, paying for) the phone and is pretty reliable.

E-mails, even if they are delivered at once (which isn’t guaranteed) are not guaranteed to notify the user at once (see for example this excellent article (and some feedback here) from the Modern Nomads folks on this question). Not so with instant messages – they, unless the connection is lost and the sender doesn’t notice this or, if it’s using a central dispatching server and it’s heavily overloaded (more on these problems later), promise really instant message delivery and notification.
