In an announcement on the official WordPress blog, the dev team have released some statistics which state that 10,000+ plugins in the WordPress repository have been downloaded over 100 million times. In addition to that, WordPress 3.0 has also been downloaded over 3 million times.
WordPress 3.0 Thelonious passed 3 million downloads yesterday, and today the plugin directory followed suit with a milestone of its own: 100 million downloads.
Just like Firefox add-ons, WordPress plugins too have been a very integral part of the popularity of WordPress. WordPress has a huge community of developers and contributors who have made this possible and there is definitely more in store with the latest version of WordPress taking a CMS approach.
I am also proud to say that my WordPress plugins have been downloaded around 400,000 times which is definitely a great number. I am very sure that other contributions and plugin developers will be proud of their achievements too.
