InfoLinks Tag Cloud

I'm a little unsure as to how the new InfoLinks Tag Cloud will impact on my AdSense earnings, and so I am contemplating its implementation.

Thoughts, comments, anecdotes?

Shouldn't this depend solely on your ad placement ? I'm wondering here but could you give more information ?

I have tried the tag cloud but it has a very low CTR but nevertheless it helps in the overall earnings in Infolinks. Maybe it is just the placement. i am still on the process of experimenting on the tag cloud.
