Time for some tech (and a good news start-up story). A new type of search engine launched yesterday called Topsy. You may be saying "I have no need for a new search engine. I have a perfectly good one already." True, but for reasons you probably don't want to know, Google, Yahoo and others can't really keep up with all the content being added by people using Twitter, Facebook, Digg, et al.
Topsy is different, and the most lucid explanation of what it does can be found right on Topsy's About page:
"Topsy listens to the conversations taking place all the time on the
living, social web. This is the rapidly growing, exciting world of
Twitter, Blogs, Flickr, Digg, Yelp, Identica and many other
communities. People use these communities to share reviews, opinions,
messages, comments and discussions about things. Topsy indexes those
things. Topsy indexes what people are talking about.
When you search for something on Topsy, such as "free music",
it finds snippets of conversations that match what you're looking for.
Topsy results are the things people link to, when they're talking about
your search terms. Topsy ranks results based on how well they match
your search terms, and the influence of the people talking about them."
That's right, Topsy is the world's best gossip. It mills around the globe, paying attention to what everyone is tweeting about, then tells you just the good stuff you want to know about right now.
What's even more interesting about Topsy is how agile and committed its founders are. I first met Vipul Ved Prakash and Gary Iwatani when they were building their last company, Cloudmark. Over the past three years, I watched them tweak and retweak Topsy endlessly, while always looking for the right market "wave" to show up. Less patient and less experienced entrepreneurs would have launched when the product was ready; they chose instead to launch when the market was ready. I hope they are good surfers--this is one monster of a wave.
