Best Websites to help discover Topics

[xoffie]

Hi

I know I can use Twitter and latest posts on Google & Blogs, but I was wondering what are the best tools at the moment to use if you are looking to write about up to the minute information about a certain topic.

Say the topic is London, is there a website or tag cloud to understand what people are saying about London right now? Anything better than Social Mention?

Note sure if this is exactly what you are looking for, but I found this site.  It aspires to do this for the consumer.
