I've been using http://www.sparrho.com throughout my PhD (in Biochemistry) and I was so impressed with its recommendation engine that I joined their team last year. We've been making a lot of changes to the Sparrho platform lately, including adding a pinboard feature to help lab groups and journal clubs coordinate their reading and keep their comments in a single place. Our database are updated hourly with papers from 45,000+ sources from all scientific and engineering fields, including arXiv. Most of our users set up Sparrho email alerts to replace journal eTOCs/newsletters, RSS feeds and Google Scholar alerts. I'd love to hear what you think! Free sign up here: http://www.sparrho.com
