Jabber is best known as “the Linux of instant messaging” — an open, secure, ad-free alternative to consumer IM services like AIM, ICQ, MSN, and Yahoo (see the IM quickstart). Under the hood, Jabber is a set of streaming XML protocols and technologies that enable any two entities on the Internet to exchange messages, presence, and other structured information in close to real time. — jabber.org
I just started trying jabbers and am loving it now. If you are like IM like MSN, Yahoo, AIM, ICQ, GoogleTalk etc etc, I believe you’ll like jabber.
Talkonaut, OctroTalk, IM+ etc basicall are jabber clients which are running on mobile, so we can use it for most of the popular IM services.
With Transport service, we can communicate between different IM services like googletalk, msn, yahoo, aim and other jabber services. There’s even SMS transport service. It’s great because we love one-for-everything.
For mobiles, octro, gtalk2voip/talkonaut can do this job.
WebBlog, PodCast, Twitter … I believe jabber will be The next hot spot.
JBother is a Java client which has almost all functions. It’s good if you have firewall problems.
Right now, most of the jabber clients only have IM function, no audio yet. OctroTalk on mobile is good for audio. People are developing audio function now.
If you like Gtalk2Voip, then you can even use jabber for VoIM, even with sip. Jabber will be truely for everything. I believe that’s the future.
You can find a lot more information at jabber.org.
I love Jabber service, and will be expecting whatever new coming.
