Mendeley stole my heart this summer. After a lackluster relationship with EndNote, I was lured by Mendeley’s polished UI and syncing features. Its social-networking-for-geeks encourages a little extroversion among the shy. I love the delinquent rush of highlighting text and adding sticky notes to PDFs. Now the Mendeley-powered Reader Meter provides an opportunity to stand in awe of scholarly giants in real time.
