First thing you realize when you take up a task of information gathering for your MBA is an effective way to save all those different links. Just discovered http://del.icio.us where you can online bookmark your web pages that are interesting. No need to add bookmark into your windoz and be stuck with them on the computer.
Also found out two more similar services (1) http://digg.com/ and (2) http://newsvine.com
Both digg and newsvine are new post sites where you can post news and comments/notes which are then published just like blogs. Give these a shot. You will not regret it.
