Two million .au domains!
We received an email a few months back from auDA, the Australian Domain Authority, saying that .there are now over 2 million .au domains! Given our population, this is roughly one domain every ten people! [corrected – Ed!]
For comparison's sake, there are now well over 96 million .com domains, according to Domain Tools
WordPress is growing
It may interest you to know that WordPress.com asserts that there are now 53 million WordPress sites in the world – about half of them hosted under wordpress.com. I've seen the figure of 4 million also mentioned, but regardless, there's no questioning WordPress has hit the top at this point.
I think this probably means that WordPress is now the most common CMS used in the world by a fairly long shot. If you're interested in seeing statistics on CMS usage, there are some here.
