Lean is a website that tells you what an article is really saying. By revealing sentiment information about an article the reader can see exactly what the author is trying to convey with their piece. While by no means does it signify that the subject of the article is good or bad, it does tell us about the way the piece is written.
Users can search through five fields: politics, entertainment, finance, technology and sports. Their results include links to numerous RSS feeds, articles pertaining to their search topic and graphs showing the daily sentiment of the search topic and historic data regarding that same topic.
To use, just type in a search term, pick a topic and LEAN!
