I want to track links using streaming API. Ideally I would like to define "http://twitter.com" and get all statuses that contain this url, both shortened (for example http://bit.ly/reXnK3 ), and full (http://twitter.com/dev/api/help.html). Any way I could achieve this? Currently it seems that the "track" method doesn't support URLs. Or am I missing something?
p.s. I know about Search API and about BackType, but I would prefer to use Streaming API, since it's real-time, and doesn't have rate limitations.
