Topsy Becomes An Even More Powerful Alternative To Twitter’s Offical Search Engine

If you've ever tried to use Twitter Search, you know that it's got some pretty serious problems. First, the site only lets you search back through a couple weeks of tweets. Even worse, the service doesn't seem to employ any relevancy algorithm to speak of â€" you just see the most recent tweets that contain your query's keywords, regardless of who said them (which oftentimes yields junk and spam). Today Topsy, the startup that views tweets as the currency of the web, is launching a handful of new features that improve on the official Twitter search in almost every way. Up until now, Topsy has been based entirely around links. When you visited the site, it would prompt you to enter a search query, and then would display a list of links most relevant to whatever you searched for. The links are ranked by the number of times they've been retweeted, and also by the influence of the people who have tweeted them; the site actually keeps track of the number of retweets each user typically gets to establish their overall reputation. Now, Topsy is taking this reputation system and extending it beyond just links, allowing you to search for both photos and tweets that don't contain links at all.
