Topsy launched earlier this week claiming to be a “search engine powered by tweets” and promising “a new way of looking at the Internet”. “Topsy sees the Internet as a stream of conversations” it claims, “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.”
Basically it seems to return a series of blog posts that people have linked to on Twitter. Topsy also seems to search Digg, Flickr, Yelp, blogs and other communities in an attempt to return results that are relevant now. However a search on Manchester United returned a stram of stories talking about “tonight’s final against Barcelona” when the final was last night so their results are already out-of-date. Compare the same search on Google news or Twitter itself and you’ll find pages of up to the minute news, articles and blogs.
So it seems Topsy has some way to go yet. Whether they’ll make a dent into Google’s 90% market share remains to be seen.
