In a post to his PhotoMatt blog, Matthew Mullenweg, creator of WordPress blogging software and WordPress.com, has announced interesting statistics about browser usage at WordPress.com, one of the most important blogging services available, the 69th most visited web site on the WWW according to Alexa and about 11 million page views a day according to the very reliable Google Analytics.

According to the post, Firefox takes about 30%, which is nice considering it is a blog hosting site with content (and visitors) as diverse as one could imagine. The results come from 115 million visits or roughly a month worth according to Matt.

However as usual with web statistics, it is almost impossible to make any further conclusion based on a single site results and even harder without knowing WordPress’ demographics. As diverse as contents are at WordPress.com, it’s hard to say much about its distribution by topic besides what its tags page tells: life, music and politics are the most used tags while technology is just the 19th.

Not surprisingly, WordPress.org, the open source software project’s web site shows a completely different profile with about 53% of visitors using Firefox and 37% Internet Explorer.
