This month was a pretty good month for WordPress.com as they got many new features sorted out, I wonder how they will be able to top it next month.
2,000 more blogs were created in September, over August, 4,000 more users, 100,000 more posts, and over 15 million more page views.
Here are the stats:
In September you guys created about 58k blogs, 61k users, switched themes 261k times, 1.3 million posts, 190k pages, 939k comments, 3.4k support requests, 254k file uploads, and around 63.7 million pageviews. (Not counting admin section, images, CSS, RSS feeds, etc.)
I would say that WordPress.com is doing well, and shows no signs yet of slowing down.
