Google is indexing my tag cloud should i leave it or do something

For some reason google is indexing all the words in my tag cloud, Here have a loook

http://www.google.com/search?hl=en&q=site:www.gl-science.com&start=10&sa=N

Theres no harm in this as my normal posts have still be indexed and by google indexing my tags I have a lot more pages indexed in google.

But my only reservation is will google penalise me in any way for this r does this have a drastic effect on SEO.

If you advise me to take them off, could you suggest how.

Personally I dont see any harm, but im not sure if it is allowed.

Thanks for your help

 

That's new. But when you tag clouds get indexed, doesn't that get your posts in those tags indexed later on?

 

What is a tag cloud? By following your google link i see links to pages with some useful content.

If you look on that page to bottom left it says tags,

Whenever yu click on a tag it goes to articles related to that tag, google has indexed all of those tags, Thats what i mean

 

No it's not a problem i have checked your links and it's even good to have those pages in the index after all
