You nailed it here ...It takes time to build a knowledge-sharing network and develop a sense-making discipline.

Thank goodness 7-8 years ago I cobbled together some tools that worked for me ... and stuck with it. Now the knowledge content flows through like clockwork and I get to reap the benefits.

A little overlap here but my current PKM toolkit consists of Feedly, Pocket, Evernote, OneNote, and Twitter. Wish I could put some discipline around a to-do system though.
