It might even be older according to the main page ("mostly written in 2001")[0]. Sure would be helpful if the author included a publish date. Many blog entries (and stack overflow type solutions) need time context (it may have been the solution/a reasonable position at the time)
You can tell the writing is very old because it mentions .ibm as an example of super well-known and wealthy corporation. No mention of Google nor Amazon.
You're right, it could be much older. I thought 2011 seemed likely because that's the earliest the web archive has and that's the year that the new gTLD program really got rolling. However, it looks from some of his other content that he might have been referring to discussions that were started in 2000 and 2001:
Given the reference "I wrote a satire of issues around this some years ago" for a piece posted in 2005, I suspect the 2010 / 2011 year is reasonably accurate.
