I'm looking for a particular solution. Maybe it already exists. I want to receive notifications about Tweets from a certain user. But only when the Tweet contains certain words. I could use it get notifications of live shows. I would simply have to enter a username and some keywords, like... live, show, EST That way it automatically ignores all the tweets that I'm probably not interested in. Hashtags are probably not sufficient, unless all the tweets I want to filter out have a special hashtag. But that's not going to happen. Is there an existing solution I don't know of? How would I accomplish this? Can I hook into the Twitter app. Or Twitter API. All ideas are welcome.
