Very slick UX and very informative as well! I would love to be able to create custom topics, such as 'D3.JS' and generate timelines with top tweets.

Quick question: how did you obtain the real-time metric "# of tweets per hour"? Are you sampling to determine an estimate using the Search API, or do you have access to a proverbial "firehose"?

We're actually using the Twitter Streaming API, which has pretty high limits even with access levels lower than the full firehose.
