Socialseek has released a desktop application that lets you search for a topic, item, brand or company across news sites, blogs, Twitter, YouTube, Flickr, and events. You can also track mentions of a particular search query by city and receive charts that show trends on popularity of a topic across websites, or Twitter. The ability to crawl social media sites and websites for a brand can be valuable, but what I find useful about Socialseek is the ability to track an item over image sites like Flickr and even event sites.
