Who said you couldn’t reinvent the wheel?

Business Insider is calling it “one of the best startups to launch in a while.” PandoDaily, Silicon Valley’s digital destination, is calling it “the social aggregator we’ve all been waiting for.”

So what is it exactly? It’s RebelMouse and it’s arguably the next biggest thing in social media aggregation. RebelMouse has taken the three most sought after social media platforms (Facebook, Twitter and Pinterest) and merged the three together. Your RebelMouse page would very closely resemble a Pinterest-like layout, but instead of images you get snapshots of your social activity. Invite only and still in Beta, it’s quickly catching on among users.

RebelMouse was founded by former HuffPo CTO, Paul Berry. With RebelMouse, Berry shows a keen ability to take what’s out there and give people a better way to approach it. Everyone already uses Facebook and Twitter. They’re different enough for serious marketers to frequent both sites, but not similar enough for them to choose one over another. Then there’s Pinterest. Even if you’re not a Martha Stewart DIY maven, you can appreciate the functionality it offers; clearly, the functionality and design are coveted industry standards that have lead to pop-up copycat sites like Manteresting.

RebelMouse takes what you love about all three of these platforms and gives you a better way to approach the two that matter the most – namely, Facebook and Twitter. But unlike Pinterest, which users frequent for their own visual gluttony, RebelMouse is designed to help screen other people. So while it looks like Pinterest, you’re never really on RebelMouse for yourself. You’re on there to take a peek at other people and better gauge their interests, preferences, history and more.

Sure you can go through their respective Twitter and Facebook pages, but that would require visiting two separate pages and then sifting through a whole lot of status updates. RebelMouse is easier and faster.

Use RebelMouse to follow lead companies, competitors, industry experts and target clients. Beyond competitor analysis and sales goals, you can also use it to further educate yourself. The capsulated updates provide a clean summary of relevant content, minus the static brought upon by open Twitter conversations or Facebook wall posts/comments. However, some exchanges are beneficial rather than just static. In those cases, you can invite others to collaborate on your page so that their messages show up on your RebelMouse stream. This, by the way, is great for content curators and other collaborators.

If we’re looking at trends, we see that RebelMouse has become an instant hit because of two trends principles we’ve been highlighting. The first is the social web. The social web hinges on a communal social experience. The more that a system can bring people together, the more it flourishes. The second touches on content curation. We’ve seen a sharp spike in content curation and its relevance. Curating content isn’t just about amassing data; it’s about the potential to showcase relevant data and to make it easier to sift through.

Future startups can learn from RebelMouse when it comes to creating a viable social tool. But beyond social aggregators, innovative startups are also proving to be quite successful. Take a look at Makerbot, a machine that can make you anything you want – and an idea that was proposed in the 2009 Humanity+ Summit. And then there’s Dwolla, which lets you send money without relying on cards or fees. Two very different businesses, but like RebelMouse they both give you a better or new way of doing something that has already proven to be successful.
