Well it not too far high-tech. Actually it’s basically a modern-day advance search engine. Like Google. But on a smaller scale. What so unique you ask? Well twitter has a pretty uncomplex search engine in their website, so TOPSY decided to change that. TOPSY created their own website built for exactly that. It shows you the trends of tweets, most commented, and you can obviously search for tweets. You can use their advance search engine to be more specific. Such as, these words, none of these unwanted words, search within a site, search within a twitter user, …it goes on and on. Well have fun!
