It would be just great to be able to put a png image reproducing the
text cloud tag generated by someone's selected (shared) RSS feeds.

I mark all publications of interest for my lab and would like to post
the resulting cloud tag on my blog (found under 'Trends') so they can
immediately see if there are items of interest for their topic.

Now I screen shoot the tags and put the image manually on the web

Sure this could be done online and added to teh google engine .

Thanks for feedback if this already exists !
