PubSub

Came across an interesting new service called PubSub that does real time searches for keywords and phrases. Unlike a search engine, it does active scanning. They are currently claiming over 9 million sources and 925 new items per minute.

Many years ago, I used to subscribe to a news digest service that sent a daily fax with headlines based on keywords you provided. This seems to be the same sort of thing, but using computers instead of editors, and in real time. You can add a widget to your browser (either Firefox or IE) to get results that way, or use Atom/RSS/XML and get the results in a newsreader.

The Wall Street Journal picked up PubSub as a source being used by day traders to trade on momentum by picking up early notice that something was being discussed.

Interesting and free - give it a try.
