The Techcrunch extension allows you set alerts regarding the topics that you are interested in.
TechCrunch was founded on June 11, 2005, as a weblog dedicated to obsessively profiling and reviewing new Internet products and companies. In addition to covering new companies, TechCrunch profiles existing companies that are making an impact (commercial and/or cultural) on the new web space. TechCrunch has now grown into a network of technology focused sites offering a wide range of content and new media.

· Alerts (unread count) for new articles

· Updates every 60 seconds
· Easy sharing via Twitter, Facebook and Digg (with Bit.ly urls)
