Follow these steps to to create your own tag cloud.
Create a subpage to collect the user tags like the current page. For each tag, create a subpage with the name of the tag. Insert into the subpage, the following contents by substituting your user name and tag name:
((Collapse top|...tagname... subpages)) ((Special:WhatLinksHere/User:..username.../tag/...tagname...)) ((Collapse bottom))
This will create a basic listing of all subpages using this template. See /map for a more advantage example which includes custom navigation on top of the basic tag listing.
Add the template to any userpage:
((User:...username.../tag/...tagname...))
This approach works across users. More than one user can share the same tag.
