Wow!
@snikket_im just started their new federated instant messaging hosting service (based on #XMPP) for everyone.
This can really be a gamechanger for instant messaging.
You can bring your own domain name if you want to.
This means: for about 5.50€ (6$) a month (according to the website) you get ten instant messaging accounts for you and your family/friends using your personal domain name (not included).
And you are able to talk to every other XMPP user out there.
