I rely heavily on del.icio.us (delicious.com) and would like to post select delicious links to Tumblr. This can easily be done by feeding the RSS feed for my "to:tumblr" delicious tag into Tumblr.
However, I want the post that I send to delicious & Tumblr to be tagged in the same way on both sites.
The delicious API supports outputting tag data, but I don't believe the Tumblr interface as-is pulls that data.
What's the easiest way to cross post between delicious and Tumblr? Perhaps a fancy bookmarklet that lets me decide if I want to post to one or the other and posts tags to both?
I tried Ping.fm (now dead) a while ago, but I don't believe it was pushing the same tags to both services.
