Google announced they have updated hot trends / searches to add images, news stories, the volume of searches and now they also cluster searches together to form a single keyword group.
For example, Apple is currently a Hot Search but the related clustered keywords are wwdc, apple store, ios 6, wwdc 2012.
That being said, how useful is this tool for SEOs? A WebmasterWorld thread has Tedster, the forum administrator, saying:
I stopped making use of this feature a while ago - except for sites that are chasing the hottest search traffic, I see it as more of a curiosity than a useful feature.
Here is a picture of the new Hot Searches:

So what do you think? A useful tool for SEOs?

I think Tedster is very much right...

I think, if you have a page with a good standing in Google News, you can try to get some buzz. But for a "0815" SEO it´s not more than just "interessting"

I can't believe Google still has this feature going when they have removed tons of useful features in the last few years. As tedster said it is a cruiosity, nothing more. Something you look at maybe once every 2 years!
