This month our first Tumblr theme, Single A, passed 30,000 installs. We submitted the theme to Tumblr on April 1st. It’s rather humbling that over 30,000 blogs are using it less than 6 months later.

I’ve been using Tumblr since December of 2007. The community here is incredible and it’s you, the users, who I’d like to thank first and foremost for your support. We listen to your feedback and have ideas in the works for future versions and themes based on that feedback.

I’d also like to thank the Tumblr staff for their support and guidance as we worked on our first theme. Last, but not least, this milestone would have never been achieved without Graham, Amanda, and Jessica. They are the people behind the development, design, and support of the theme.

If you have an idea for Single A or a future theme, send us a message. We look forward to hearing form you.
