The size of the word cloud is not proportional to the number of articles containing the word.

i.e. on my site, the word science is bigger than the word gender though I have 2 articles for the former and 4 for the latter...

Nice and pretty but does not allow the use of CSS style attached to a template...

... Does not work if you did not keep the original Joomla! categories. A bug fix is expected sometime in the near future.
