Eaton web has finer breakdowns. It's a slick discussion board. This could be an in-house daily bulletin. Perhaps combine it with a rating system to pull the good stuff to the top. A good way to find worthwhile weblogs is through the links of a weblog you trust.
Readers rate articles on the spot.
Ratings yield points. Points permit posts. It seems a little complicated for the wideopen Internet but might have application in-house. A guerilla team of web-head kids could get a full weblog system up and running on a corporate intranet in no time. Imagine populating a knowledge management system organically.
