The budding rivalry between social networking giants Facebook (NASDAQ:FB) and Twitter has been well documented and for good reason.

Each respective firm has its own strengths in the booming social arena. Facebook is the undisputed top dog when it comes to keeping tabs on your network. Twitter, on the other hand, is increasingly trying to brand itself as the de facto source for online news and discussion. What these tech giants have in common is an ambition to capture an ever-increasing slice of online advertising dollars, which is the genesis of the Facebook-Twitter rivalry.

And in keeping with this storyline, Facebook recently fired another salvo against Twitter by rolling out a new tool that should ideally help it encroach upon its journalistic crown. The stakes are understandably high, especially considering Twitter's long-awaited IPO is getting closer by the day.

In this video, tech and telecom analyst Andrew Tonner breaks down Facebook's recent moves and its potential implications for both of these fast-growing, new-media titans.
