Can you explain how you'd use Gnip in this instance? From reading the API docs, it doesn't sound like you can do anything with Gnip + Twitter other than get tweets from / to a particular Twitter user. So you can't get keyword-filtered results from the public timeline, I don't think. Am I missing it?

You're 100% correct. But I'm hoping they'll add the ability to use filters on the whole firehose in the near future.
