I often find a brilliant blog, see that it’s not a Tumblr, and realize that I’ll never visit it again. Tumblr and Techmeme are my only feedreaders. If you’re not getting me there, you’re not getting me.
A service that could Tumblrize RSS feeds would make my day.
Tying Postling’s publishing tools with an RSS reader is something we can do pretty easily, so you could plug in any RSS feed and reblog the feed items to your Tumblr (or Wordpress / Blogger / Typepad / Squarespace / Drupal or Twitter / Facebook status). The biggest issue is that Tumblr doesn’t expose it’s dashboard or notifications via API, so we can’t recreate the full experience. Fred Wilson has told me Tumblr omits this functionality by choice, sadly, but one can always hope they change their minds.
