Your Tumblr Tag List: Instructions
Here is an easy and quick way to get a list of all tags you entered in your posts with a little bookmarklet.
Drag the following link to your bookmarks bar: Your Tumblr Tag List Bookmarklet
Go to your dashboard and click the “New Text Post” button.
Click the bookmarklet.
A new page will be opened and all your tags will be listed.
You are the only one who can reveal your tags with the method mentioned above. No personal data will be stored or archived on my web server. This is just for fun. Tumblr’s own API is probably way better to get a tag list, though.
