I just submitted this to Tumblr’s Get Satsifaction page. If you agree, please follow the link and add your vote to the feature request.
Google Analytics shows a really high bounce rate on my Tumblr. I recently tweaked the SEO which is bringing in more visitors but most read a single post then leave.
I’d love to see an automated related entries feature that would parse through tags and text to provide related entries on each page—something to keep those random visitors on the site longer.
