The results seem valid in most part for professional and manager level employees, but i would like to see if the results would be different in a more procedures base work. I work mostly with government employee training. I don't think, In those organisations, that the agent level employees learn as much informally. My guess his the rely more on official sources for their learning: email, memos, team meeting, formal learning etc. They are not using collaborative tool or self research for their work at all.

It would also be intereseting to see how each level of employee describe what his a learning content. My guess his we would not be the same for all.

Ps: sorry for my english, it his not my first language...
