With whom, and how often do you share what you are currently learning?

Good question
I will share my learning with my team and sometimes I will post it in the intranet site to relevant audience whenever i find it interesting.

Knowledge dissemination and experience sharing are a matter of continuous processes that can not be limited by time or a place; when a moment of a show case is arising you have to take the initiative to express yourself among who ever might be concern or interested (the targeted group usually will be members in your team, peers in the corporate, colleagues,...etc.) what you may think is right and helpful while keeping yourself ready and flexible for a further elaboration and discussions for give and take with your audience.
