Tumblr v.5 introduces the Theme Garden. It does what Tumblr Themes tried to do, but better. If you’ve made a theme you’ve submitted here, you should submit it there too, and if you’ve made a theme you haven’t submitted here, you shouldn’t bother with Tumblr Themes, just submit it to the Garden. If you’re looking for a theme, this is probably still the most extensive repository, at least for a little while, but keep an eye on the Garden, from which you can install a theme in a click. Much more convenient than Tumblr Themes.
This, then, means that there’s no reason to update this repository any more, but it will still remain available. nostrich:
The crushes are neat, but this is my favourite new Tumblr feature: the theme garden. It does more or less exactly what Custom Themes was made to do. And though that now renders my favourite internet project (though Simen took the reins a month or so ago) to date more or less defunct, I’m glad to see it go in favour of Tumblr’s effort, which I always knew was coming. (I have no idea if Simen will continue to maintain CT.)
