With the huge success of Facebook (NASDAQ:FB), entrepreneurs have been looking for ways to add social elements to niche categories. Some examples include Spotify and even Pinterest. So why not do the same for sports? Well, that’s what Eric Goldstein and Dave Grossman did. They created the popular app, SportsYapper. It’s becoming the way sports fans can cheer or commiserate about their teams.

Think of SportsYapper as the “second screen.” That is, it is what people look at when their watching television. The app is available for Apple’s (NASDAQ:AAPL) iPhone and iPad as well as Google’s (NASDAQ:GOOG) Android.

In fact, SportsYapper caught the interest of Mark Teixiera, the Yankees first basement. He has since become an investor in the venture.

A key to SportsYapper is that it allows people to focus on their interests, without having to deal with pain of hashtags. In other words, there will not be a flood of posts, such as from the often-annoying play-to-play updates on  games. This has actually become a big problem with Twitter. Oh, and SportsYapper lets its users make posts of up to 300 characters.

As with any new social app, it is impossible to say if SportsYapper will be the category killer. Expect to see other operators to launch.

Despite all this, the market looks primed for a sports-focused social network. And so far, it looks like SportsYapper has the first-mover advantage.
