Trendpedia, which is powered by Attentio, a Brussels based market intelligence company, seeks out trends in the blogosphere. It’s basically a simple search engine which scans for trends in blog posts and then composes graphs, called Trendlines, giving you a clear visualization of what’s hot on the internet. You can search via keywords or phrases. Once you click on a graph, articles are collected by date and organized into tabs, allowing you to see how spikes occurred. Additionally, searches can be linked to your site, so you can monitor which topics are getting the most buzz. Popular trends from the week and month are listed on the homepage.
