Twitter Venn helps you track the relative popularity of various topics on Twitter and how these conversations overlap with each other. The service creates an interactive Venn Diagram for your set of terms using data from Twitter Search. Each dot represents a conversation and you can hover the mouse over any dot to read the corresponding tweet message.
Here’s a sample Venn diagram for the terms "embargo, techcrunch and arrington".

Hi Amit. I’m Jeff, the creator of Twitter Venn. Thanks for the post. One minor correction – the dots don’t have a one-to-one correspondence with tweets and hovering over them doesn’t show that particular tweet. The tweets shown at the bottom are randomly chosen from the selected region of the diagram. The selected region has a gray background and you click on a different region to select it. Thanks again !
