How do I receive an alert or create a feed for when a specific Twitter account tweets a specific keyword(s)?
For example, the author of a software application I use apparently does not have any type of feed dedicated to the updates for that software. I'd prefer not to follow his personal feed and monitor for that 1/100+ tweet mentioning the software update. I'd prefer to be notified in some fashion when they tweet a specific keyword. RSS is fine. Other tech/feed is fine.

There used to be a link to create RSS feeds on search.twitter.com, but it has disappeared. Fortunately the link itself is still working. You can insert any search operators you want (and use the from: tag to specify the user).

...would search for tweets from ladygaga mentioning the word "moment".
