Last Thursday, September 22nd, I received a message from Foursquare letting me know that it was my second anniversary on their site. It was while I was at the Digiday conference on Social Media and that seemed somehow appropriate.

Last year, PodcampCT took place on the 4th anniversary of me being on Twitter, October 16th. This year, I will be in Rochester, MN on the day before a conference on Social Media and Healthcare starts on the 16th.

On Facebook, I installed Timeline last week, only to be told that today, September 26th, is my fifth anniversary on their site. Friends have expressed surprise that I've only been on Facebook for five years, but I point out that it was about five years ago that they finally opened up Facebook to people with email addresses other than at schools.

With all of this, I started looking around for other online firsts for myself that I could find. The earliest I could find was a Usenet post I put up on July 11, 1982. According to Lambda, I joined their MOO on 12/30/1994. On Jan 23, 2002, I joined Ecademy and the earliest blog post I can find there is from 8/21/2002.

Also 2002 is the earliest post I have on Livejournal, dating March 13, 2002. It was based on a discussion I had had on a different MOO.

Over on the political blogs, the earliest post I find on DailyKos was November 10, 2003. This is followed by a post on Greater Democracy on December 10, 2003. I suspect there are a bunch of other posts from that era that I can't find, which is partly prompted me to create Orient Lodge in 2004 as a repository for some of my writing.

There are plenty of other online anniversaries, but at least right now, these are probably the most significant.
