Today’s big idea is a graph of trending keywords. I know there are lots of sites which display trends in various formats, for what its worth my favourite is twitterfall. What I have in mind is slightly different – it would display trending keywords in graphical format, like pie charts of the distribution of the top 10 or line graphs showing what ranking a certain keyword has had over time. Of course, it would need to be completely configurable – i.e. the user could select type of graph and which keywords to track. And the ability to track keywords across multiple services would also be pretty cool (e.g. twitter, flickr, blogs, etc.).
