Yup!

Mmm. Okay, I went with what Guillaume suggested, and made a xar and jar 
out of it, and contributed it as a plugin: 
http://www.xwiki.org/xwiki/bin/view/Code/TagCloud

But I do see your point about eliminating the java-side of this. The 
logic isn't that hard to implement as a groovy script or velocity macro, 
I guess.

Well, if it were only a page (or a "snippet"?) it might be easier for 
people to include it  wherever they want, including in panels? But you 
guys more familiar with the level of expertise and mode of use amongst 
the xwiki masses, so I leave this for you to decide :-)

Also, I agree with Sergiu that it would be better if the font size would 
be calculated relatively to the number of ocurrences. Good thinking!

I just did an update there.

Sure!

I'm not sure I understood this. Do you want me to commit stuff to svn, 
or attach stuff to the JIRA issue?

Thanks for the enthusiasm on this! I have a couple of thoughts on how 
tags currently behave in xwiki, but I'll try to write a separate email 
on that subject a bit later.


cheers :-)
