In the past we used ZoomClouds to generate Tag Cloud for our Tumblr, however the service is experiencing some problems.

Via Angela I found: http://tumblrtags.hr1v.com/index.php

With this tool you can generate a Tag Cloud for your Tumblr.

There is a main difference with ZoomClouds… while ZoomClouds, from a RSS feed, creates a cloud with possible tags (hence, it guess the tags from the RSS content), this last one builds up the cloud from the tags implemented in Tumblr V3.

So… let’s start tagging all the old post, if it has not been done before! :)
