This question was originally posted on Programmers SE. I've placed it here based on advice in the comments.
We have recently polled our company wide wiki users and found out that there are two large groups of users:
- people with lots of knowledge but (who claim they have) no time to document
- people with time but (who claim they have) not enough knowledge worth documenting
Each group covered almost 50% of the users!
How do your companies handle this? That is, how do you encourage your busiest / most knowledgeable people to share their knowledge?
