I'm one of the creators of the Tarski theme for WordPress which got picked up by WordPress.com.
Right now, 1.1.3 is the most current version of the theme on WP.com. That's... seven versions behind our latest, which means it's missing various tweaks and bugfixes, as well as various options (switching the sidebar to the other side, nifty extra default headers, etc.).
I'd love to have a "WordPress.com for theme developers" type FAQ so we know how to:
- Get our themes updated
- Make our themes more suitable for inclusion & easy update, etc. in the first place
- Contact someone technical for such things instead of spamming support with such things - a theme dev liaison, for example
In the spirit of open source, it'd be great to hear from you guys when you fix a bug in our themes, too.
