I think Seek > Sense > Share is a great framework for Personal Knowledge Management and it was very helpful to get started and think about my own process. The examples in this post and in the comments were inspiring for me to visualize my PKM-routine The most important part of it is definitely Evernote. I really recommend it to anyone who needs a central place for collected information and ideas. For 'Seeking', Twitter and Feedly are by far my most important sources.
