GMPG History to date

A few steps to date in the GMPG history are as follows:

1992: The GMPG was first mentioned by Neal Stephenson in chapter 3 of his book Snow Crash.
2003 March: The Founders (Tantek Çelik, Eric Meyer, Matthew Mullenweg) met at the SXSW conference in Austin TX USA. Inspired by blogs and blogrolls, they decided they wanted a simple way to express human relationships on the Web, and developed the initial principles for XFN, the XHTML Friends Network.
2003 May: First draft of XFN and various satellite documents were written, including XMDP, a general format for XHTML Meta Data Profiles in XHTML.
2003 August: The Founders decided to create a site to house such protocols/formats and GMPG.org was born. Amongst a flurry of activity numerous documents were written and posted.
2003 September: The Founders finally find enough spare vacation and other off hour moments to polish GMPG.org, XFN and related documents enough for a limited preview.
2003 December: After a bunch of minor tweaks in off hours and last minute comments from previewers, XFN is released to the public.
2004 August: GMPG releases XFN 1.1 with three new values ("contact", "kin", and "me") as a poster at Hypertext 2004 in Santa Cruz, California (USA), the Fifteenth ACM Conference on Hypertext and Hypermedia.
2005 May: The 14th International World Wide Web Conference, Chiba, Japan. GMPG's paper on XMDP accepted for the Poster Track of WWW2005.
