Like most people, I use Instant Messenging (IM). I have accounts on all the main providers (MSN, Yahoo IM, AIM, ICQ and Jabber) but the one most of my friends use is MSN. It seems that MSN is the most popular IM service over here in the UK, but AIM is more popular in the US.
Anyway, if it wasn’t for the fact that most of my friends are using MSN, I’d ditch it (along with the other proprietary protocols) and move exclusively to using Jabber, as its a nice, open, documented protocol with a wide range of available clients. By design, it’s decentralised – there’s no one “central” server which controls the network, unlike MSN etc.
My friend Steve recently decided to drop MSN, and another friend, Tony, is starting to use Jabber too. Along with another friend James, who started to use Jabber quite a while ago, I think we have the start of a revolution :)
