Ask HN: What would normal people do with Twitter search?

I am not a Twitter hater. I enjoy using it ( @webwright) and think it has a bright future.

I see lots and lots of people talking about how amazing realtime search is. Clearly, it's a boon to PR folks, marketeers, etc. And it's interesting from a real-time citizen-news angle. I see how it's cool at conferences/events. And it's fabulous for tracking celebrities.

But can someone run through some use cases showing how normal people would use it every day?
