As stpeter mentions in the 16th issue of the Jabber Journal, it has been 5 years since the Slashdot story on 4 January 1999, in which jeremie announced the existence of Jabber. To all involved with Jabber since then: congratulations!
Although I wasn't involved with Jabber at the very beginning, my years of experiencing Jabber have been pretty exciting. I have seen Jabber grow, attract lots of both developers as users, and I even helped develop Jabber Enhancement protocols. Just like stpeter and hildjj I find it intellectually stimulating to think of (new) uses of Jabber. Everywhere. I hope to think of, and test out, more of that the coming year and beyond.
