Jabber is an OpenSource InstantMessaging system at first blush. Originally it started off as a way to connect all the major InstantMessaging systems together. But it became something more cool than that. It's a push transport layer. It's XML based.
http://www.jabber.com is the corporate face of the jabber project. (Jabber, Inc.)
Google now uses Jabber for Google Talk. http://www.google.com/talk/
It's really good. -- Sunir@jabber.org
Dave, this may explain a few things. Keep in mind it's really a lack of time that's tying up Jeremie Miller, the Jabber.org leader. From talking with him, I believe he knows what he is doing. On the other hand, I don't believe Jabber.com has the right intentions. (P.S. I feel somewhat comfortable posting this because this e-mail has already been distributed to the Jabber.com open source advisory board.)

If they are, then in what sense > are the cards close to the chest? Released source code doesn't make a *project* open, merely the program. To make the project open, input from the userbase must be accepted. Even better, the distinction between the project and the userbase should become fuzzy. That is, I as a user should be able to do development when the program does not meet my requirements. Moreover, since this application has no value by itself, but as a network, my changes must be accepted by a significant portion of the users to provide value. Without entering the core stream, this is next to impossible. The Jabber project is currently developed soley by a handful of core developers. Project planning is downstream only; announcements are made on http://dev.jabber.org as to what they are doing. But there is [no] feedback channel to get things integrated into the release schedule short of petitioning them on the jdev groupchat on jabber.org. Furthermore, as Jabber.com owns all the code, there is a significant wall to upstreaming patches to the open group. They have a stable version of the server in house, yet the open version is not (*). There is little reciprocity. Worse, they have tied up all the open source developers with their internal projects. [(*) A rather poor decision as many people have concluded that Jabber isn't working, as the open server hasn't been stable for awhile. Specifically, the transports to other instant messaging networks like AOL Instant Messenger, etc. have not worked for a long time, and they are Jabber's raison d'etre. For another famous example of this, consider Mozilla. Many people still won't touch it because it didn't work early on. The significant reason for the unstability has been lack of developer resources. All the users get are messages that "we're working on it," but the jdev mailing list has been empty of information on what's broken. If there were more appeals for help outside the inner circle, I'd bet things would be better.] Consequently, the project is not open. And I believe this is because of pressure from Jabber.com. I believe this is what you originally referred to as Cathedral development a long time ago, if I understand correctly. When you were comparing two differen open source development styles, not open vs. closed source. Have you ever heard of a philosophy called "Fair Process?" I have put some comments at http://usemod.com/cgi-bin/mb.pl?FairProcess An open ended organization like an open source project must maintain open communications, plus the leadership must be attentive to the constituency, or the constituency will perceive (correctly) a lack of procedural justice. Thus they will bail. SS
A personal anecdote on my experience with Jabber (extremely limited though it may be). KuroShin was one of the first places any news about Jabber appeared, in any medium. A couple of the kids who were working on it wrote up a great little article  back in May 2000, which sticks in my memory because they went through about three or four revisions of it, and I was impressed by the lengths they were willing to go to to get it right. And read the article: they really care about it's being open source.
Skip forward to LinuxWorld Expo, in San Jose, circa August 2000 (?). I was wandering the show floor, and ran into a couple guys wearing Jabber shirts. They were mid-fortys-looking, and looked very much like Management. However, I had no idea who "Julian" was, other than having conversed a couple times on IRC and via email. I said hello, and told them who I was.
Finally some light dawns. Yeah, they tell me, he's around somewhere. They wander off, obviously not giving a shit who I am.
A while later, I run into a couple kids who look about 13, also wearing Jabber shirts. I was hanging out at Linux Journal with Doc, and they came right up to me.
Pleasantries were exchanged, they were really happy to meet me, etc. I eventually asked them who the Management dweebs were. "They're the .com guys" was pretty much the answer. Jabber was bought by some company, and was clearly operating with two very different camps. I heard, in the back of my mind, a deep minor-key note that boded ill for the future.
It looks like what you're seeing now is the upshot of the basic disconnect between the very-committed-to-free-software Jabber hackers, and the very-committed-to-making-a-buck .com parasites. I'm not at all surprised to hear this, and I hope they can weather incompetent management and come out a stronger project. Watching the same basic mismanagement occur at my last company , I'm kinda sensitive to the symptoms now.
Wow, that was a lot longer than I thought it was going to be. :-)
I was just talking with JeremieMiller?, leader of Jabber.org. Jabber.com and Jabber.org just went through a significant reshuffle of its priorities. Jabber.org will be improving its developer focus now, trying to open up (yes, because of my e-mail). What I would think might be interesting is plugging something like a real time Jabber-based "WhoIsOnline" system into a site, or a network of sites. Or even updating a network of sites in real-time with each other's status using their dedicated socket protocol. Jabber is a lot more than InstantMessaging, like it's said above. -- SunirShah
Since Jabber is an open protocol, anyone can steal the entire project by implementing a better server or client that becomes the new standard. Sort of like IE took over the HTML standard. For this reason, I think Jabber is still good. --anon.
That's not true at all. There is more to supplanting the standard than making a technically better server. In fact, you don't even need a technically better server, just a more popular one. In fact, look to IE for an example of that. Certainly IE was not technically better than NetScape when it began taking market share. -- SunirShah
